My updated Big Board rankings for the 2019 NFL draft are below, plus my latest look at the top 10 prospects at every position, from quarterbacks to kickers and punters.
The deadline for underclassmen to declare for the draft has passed, and there weren't many big surprises, outside of Oregon quarterback Justin Herbert, who will now be at the top of the 2020 class.
As always, a reminder that height and weight listed below are based on what we have from schools. We don't get official numbers until the NFL combine next month.
Note: One asterisk denotes the player is a junior, and two asterisks denote the player is a redshirt sophomore in 2018.

1. Nick Bosa, DE, Ohio State*
Height: 6-foot-4 | Weight: 263 pounds | Previously: 1
I don't expect the core muscle injury that ended Bosa's Ohio State career to affect his draft stock. He could go wire-to-wire as my top-ranked prospect. The last guy to do that? All the way back to ... 2017, when pass-rusher Myles Garrett ended up going No. 1 overall. Bosa is an elite pass-rusher who is advanced for his age in his technique -- you can probably thank his brother, Joey, and dad, John, both former first-round picks. He finished his Buckeyes career with 17.5 sacks in two-plus seasons, most of which were in a loaded line rotation.

2. Quinnen Williams, DT, Alabama**
Height: 6-4 | Weight: 289 | Previously: 2
Williams was one of college football's best players -- not just defenders -- this season. And it showed as he finished eighth in the Heisman Trophy voting. He dominated LSU with 2.5 sacks and 10 total tackles, and he finished the season with 8 sacks and 19.5 total tackles for loss. When I wrote about Williams after the LSU game, I mentioned his ability to use his hands to disengage from blockers. He is so good at destroying double-teams. Williams really only played one full season for the Tide, but he was tremendous. It wouldn't be shocking if he enters the conversation for Arizona at pick No. 1.

3. Josh Allen, OLB, Kentucky
Height: 6-5 | Weight: 230 | Previously: 4
I pegged Allen before the season as a potential Day 2 pick, as he broke out in 2017 with 7 sacks, 66 tackles and 1 interception. He has been underrated in this class, and now he has a chance to be a top-10 pick. Allen is disruptive, and he has the length that NFL teams love as a 3-4 outside linebacker. He had 17 sacks this season, including three-sack games against South Carolina and Penn State, and he forced five fumbles. You can see some of his quick-twitch ability in the clip below:
Kentucky's Josh Allen sacks Penn State QB Trace McSorley on third-and-6.

4. Devin White, LB, LSU*
Height: 6-1 | Weight: 240 | Previously: 3
White is one of my favorite prospects in this class, and I noted in our draft primer that he's a perfect fit for today's NFL. During a spectacular breakout 2017 season, he had 133 tackles, 14 tackles for loss, 4.5 sacks and an interception. White dominated this season, too, with 123 tackles, including 12 for loss. I love his read-and-react ability. White is not a true pass-rusher, but he could play outside or inside linebacker at the next level. He has some versatility and is extremely athletic.

5. Andraez "Greedy" Williams, CB, LSU**
Height: 6-3 | Weight: 184 | Previously: 5
Williams burst onto the scene in 2017, picking off six passes as a redshirt freshman and emerging as one of the best defensive backs in college football. He had two more picks this season. Williams has great ball skills and a long, lean frame, and he sticks to wide receivers. The third-year sophomore is the best lockdown corner in this class.

6. Dwayne Haskins, QB, Ohio State**
Height: 6-3 | Weight: 220 | Previously: 7
The third-year sophomore is officially entering the draft, and I wrote about him after he announced his decision. He could be the No. 1 pick if teams try to trade up to make sure they can get the top quarterback. There's a lot to like about him. He has a big arm, shows great anticipation on his throws, takes care of the ball and has solid athleticism (though he's not a great runner). Haskins never gets rattled, and he excels in big moments. He's far from a finished product, but the high ceiling flashes on tape. There's a long way to go until the draft, but I expect Haskins to be the first QB off the board.

7. Ed Oliver, DT, Houston*
Height: 6-3 | Weight: 292 | Previously: 9
Oliver is still a potential top pick, but people I've talked to believe he's closer to 275 pounds than the 290-plus at which he's listed, and he hasn't developed consistent pass-rush moves. That's why I have always said the comparison to Aaron Donald was unfair. Now, Oliver is still a game-wrecker and a great player -- just play the East Carolina tape when he had five tackles for loss. And his first step is one of the fastest I've seen from a defensive tackle. The pre-draft process will be big for him.

8. Devin Bush, LB, Michigan*
Height: 5-11 | Weight: 233 | Previously: 8
Bush, who hurt his hip in the Wolverines' loss at Ohio State, is a playmaker. He lines up all over the field and is always around the ball. He caught my eye early last season as a sophomore when he had 102 tackles, including 9.5 for loss, and an interception. He had 79 tackles and five sacks in 2018. I scouted his dad, Devin Bush Sr., a first-round pick out of Florida State in 1995 who had a 41-inch vertical. Bush and White are similar sideline-to-sideline, three-down players who will vie to be the first linebacker off the board.

9. Rashan Gary, DT, Michigan*
Height: 6-6 | Weight: 283 | Previously: 10
Gary was one of the first underclassmen to declare for the draft. Now he needs to have a strong combine and interview circuit. He dominates when he's at his best; he just manhandles offensive linemen. Gary has a high ceiling. The problem? Consistency. A defender this big and this talented should create more pressure and disruptions. The former No. 1 overall recruit disappears too often for my liking. Gary could play end in a 3-4 defense or three-technique in a 4-3.

10. Kyler Murray, QB, Oklahoma*
Height: 5-10 | Weight: 195 | Previously: NR
Murray is entering the draft. Now what? Well, it's still not certain he's actually going to commit to football. He could still get a new deal from the Oakland A's and report to spring training in February. For now, though, I'm treating the Heisman Trophy winner as if he's going to be in the 2019 class. And I think he has a great shot at being picked in the top 10. The knock, of course, is his size, but you can't deny his athletic ability, and he has an underrated arm. He can make every throw. I've said several times that he's one of the most dynamic dual-threat quarterbacks I've ever seen. Murray won't be for every team and every system, but if he lands in the right spot, he could be a star.

11. Jonah Williams, OT, Alabama*
Height: 6-5 | Weight: 301 | Previously: 12
It's not easy to start for Nick Saban as a freshman, and that's exactly what Williams did when he lined up as the right tackle in Week 1 in 2016. Now he has started 43 games over the past three seasons, playing on the left side in 2017 and 2018. Williams could move inside to guard at the next level, and I compared him to Washington's Brandon Scherff in our preview of the class.

12. Deandre Baker, CB, Georgia
Height: 5-11 | Weight: 185 | Previously: 11
Quarterbacks who go after Baker don't have much luck. He broke up 9 passes and had 3 interceptions last season, and he had 10 pass breakups and 2 picks in 2018. Baker isn't far behind Williams as the top corner in this class, and there could be two corners picked in the top 10 in April.

13. Jeffery Simmons, DT, Mississippi State*
Height: 6-4 | Weight: 300 | Previously: 13
One thing that really impressed me in Mississippi State's loss to LSU earlier this season was Simmons' hand usage. He knows how to disengage blockers and find the football. He had two touchdowns last season. In one game. He blocked a punt and recovered the ball in the end zone, then took a fumble 90 yards to the house in a rout of Louisiana Tech. The big man can move. Simmons, a disruptive player on the interior who could play in a 4-3 or 3-4 front, also chipped in five sacks and 12 tackles for loss in 2017. He had two sacks and 17 tackles for loss in 2018. Simmons will have to answer to NFL teams about his 2016 arrest on a charge of simple assault.

14. Cody Ford, OL, Oklahoma*
Height: 6-4 | Weight: 338 | Previously: NR
Ford moved from guard to right tackle in 2018 and really improved. The word I'd use to describe him? Nasty. Ford is a mauler who will run you over and hold you to the turf. He's likely to move back inside to guard at the next level, and he has the feet to play at a high level there. The Sooners had the best offensive line in the country this season, and four of the five could be drafted in 2019. Ford is the best of the bunch.

15. Jachai Polite, OLB, Florida*
Height: 6-2 | Weight: 242 | Previously: 17
Polite is an edge rusher who keeps rising, like Kentucky's Josh Allen, and he was the Gators' best player in 2018. He had 11 sacks and 17.5 total tackles for loss. Polite plays with a ton of energy. He's aggressive. This is his first season as a full-time starter because he hurt his shoulder in the middle of the 2017 season. He plays with his hand in the dirt as a defensive end, but I think he's probably a 3-4 outside linebacker in the NFL.

16. Clelin Ferrell, DE, Clemson*
Height: 6-5 | Weight: 265 | Previously: 20
I thought Ferrell could have been a first-round pick in the 2018 draft as a third-year sophomore. He's that good. He had 9.5 sacks last season and added another 11.5 this season. He terrorized Texas A&M and Georgia Southern with two sacks apiece and multiple pressures. Clemson had one of the most talented defensive lines I've ever seen in college football, and the Tigers could have three first-rounders in this draft.

17. Dexter Lawrence, DT, Clemson
Height: 6-5 | Weight: 340 | Previously: 14
As I wrote in my way-too-early Big Board, big-bodied guys who move like Lawrence and can eat gaps don't last long in the draft. And Lawrence has shown that he is more than a plugger -- he had nine sacks in his first two seasons. Turn on the tape, and you'll see Lawrence take on blockers and throw them aside. He's also 1-for-1 on turning carries into touchdowns. Lawrence was suspended for both College Football Playoff games because he tested positive for a banned substance.

18. Brian Burns, OLB/DE, Florida State*
Height: 6-5 | Weight: 235 | Previously: 23
Burns, who had 10 sacks in 2018, can bend the edge as well as any other pass-rusher in this class. He has a lean frame, but he's quick off the ball and can use his speed to get to quarterbacks before offensive tackles have a chance to move. Burns had 13.5 tackles for loss and 4.5 sacks last season, after 9.5 sacks as a freshman in 2016. He needs more time in the weight room, but he could grow into a 4-3 end in time. There's a chance he rises even higher after the combine.

19. Oshane Ximines, OLB, Old Dominion
Height: 6-3 | Weight: 253 | Previously: NR
When I wrote about Ximines in September, I had a third-round grade on him. He was coming off a two-sack performance against Virginia Tech, where he was explosive off the edge and also moved inside to show off his bull rush. I've changed my grade after seeing Ximines improve throughout the year -- he just dominates. He finished the season with 12 sacks and 18.5 total tackles for loss. The versatility to play outside, inside, and with his hand in the dirt or standing up is what NFL teams want. Ximines is a really good prospect, and teams are always looking for edge rushers.

20. Daniel Jones, QB, Duke*
Height: 6-4 | Weight: 220 | Previously: 25
I wrote about Jones' rise in November, and he finished the season strongly with five touchdown passes in the Blue Devils' bowl win over Temple. The most impressive trait I saw from Jones is 2018 was his ability to buy time in the pocket and use his feet to get square and make a throw. Jones threw 29 interceptions in his three seasons as the starter, and he forces the ball at times, but he mostly cut down on the poor throws in 2018 (he had nine picks). We also have to mention his coach, David Cutcliffe, who groomed Peyton Manning and is seen as a quarterback whisperer. Jones is the top signal-caller in attendance at the Senior Bowl in Mobile, Alabama. Let's see if he separates from the pack.

21. Christian Wilkins, DT, Clemson
Height: 6-4 | Weight: 310 | Previously: 21
Like Ferrell, Wilkins skipped the 2018 draft and decided to return for another season at Clemson. And like Ferrell, Wilkins could have gone on Day 1 this past April. Last season, I compared Wilkins to former Alabama defensive lineman Jonathan Allen, because he's scheme-versatile and could play end or tackle in the NFL. Wilkins had 15 tackles for loss this season, and he was one of the locker room leaders for the national champions.

22. T.J. Hockenson, TE, Iowa**
Height: 6-5 | Weight: 250 | Previously: NR
The next great Iowa tight end in the NFL? It could be Hockenson ... or his teammate Noah Fant. Fant got all the pub before the season, but Hockenson is my top-ranked prospect at the position. Hockenson put up better numbers, and he's a better blocker. He's a more complete player, though Fant is more athletic. Hockenson will be able to play right away and line up next to a tackle. You can see some of his athleticism in the 37-yard catch and run in the clip below:
Nate Stanley hits T.J. Hockenson in stride up the sideline for a 37-yard touchdown, adding onto Iowa's lead over Illinois.

23. Greg Little, OT, Ole Miss*
Height: 6-6 | Weight: 325 | Previously: 16
Little is a true left tackle. He won't have to move to the right side in the NFL. He's light on his feet and can get to the second level to take on linebackers, and he consistently overpowers SEC edge defenders at the point of attack. The former five-star high school prospect protected the blind side of Oklahoma's Kyler Murray in high school.

24. Byron Murphy, CB, Washington**
Height: 5-11 | Weight: 182 | Previously: NR
After redshirting in 2016, Murphy snagged two picks in his first college game last season, a road win at Rutgers. He's a natural playmaker with easy speed. Murphy missed seven games in 2017 because of a broken foot, but he has played well since. He had 4 interceptions, 13 pass breakups and 4 tackles for loss. The third-year sophomore isn't as big as former Huskies corner Marcus Peters, but he makes that kind of impact. He could also play some in the slot in the NFL, which is a valuable skill.

25. Jawaan Taylor, OT, Florida*
Height: 6-5 | Weight: 328 | Previously: 24
Taylor is a mauler on the edge. He has played both left and right tackle for the Gators, and his technique is still raw, but he has the potential to be the first offensive lineman off the board. Some teams might like him at guard, too, and the versatility is a plus.
