My latest Big Board for the 2017 NFL draft is live, and so are my updated position rankings.
Important to note: This is a mix of seniors and underclassmen, but early on, I separate the two so you see more senior players, who are certain to be in the draft. By "underclassmen," I mean players who technically could return to school for another season. Those are true juniors and third-year sophomores. I've denoted the third-year sophomores with asterisks.
Quarterbacks
Seniors
1. Chad Kelly, Mississippi
2. C.J. Beathard, Iowa
3. Seth Russell, Baylor
4. Cooper Rush, Central Michigan
5. Davis Webb, California
Underclassmen
1. Deshaun Watson, Clemson
2. *DeShone Kizer, Notre Dame
3. Brad Kaaya, Miami (Fla.)
4. Mason Rudolph, Oklahoma State
5. Jerod Evans, Virginia Tech
Kizer, a third-year sophomore, has moved into my Big Board. He's young, but his talent pops on tape. Mason Rudolph has a big arm and a ton of experience in the Big 12. He has 13 touchdowns passes and just two interceptions for the Cowboys this season.
Running backs
Seniors
1. Kareem Hunt, Toledo
2. Corey Clement, Wisconsin
3. Matthew Dayes, NC State
4. Donnel Pumphrey, San Diego State
5. Justin Davis, USC
Underclassmen
1. Leonard Fournette, LSU
2. Dalvin Cook, Florida State
3. Christian McCaffrey, Stanford
4. Royce Freeman, Oregon
5. Nick Chubb, Georgia
Dayes is the only new addition here. He's an experienced, all-around back with 563 rushing yards on 5.7 yards per carry. The underclassmen in this group are excellent.
Fullbacks
Seniors
1. Sam Rogers, Virginia Tech
2. Anthony Firkser, Harvard
3. Prescott Line, Michigan State
4. Jaymar Parrish, Pitt
5. Nate Iese, UCLA
Underclassmen
1. Daniel Marx, Stanford
2. Chris Herndon, Miami (Fla.)
3. Jaylen Samuels, NC State
4. Dimitri Flowers, Oklahoma
5. Khalid Hill, Michigan
Line is a graduate transfer who came to Michigan State from SMU. He has just three carries for the Spartans, but he rushed 228 times -- and caught 27 passes -- for the Mustangs.
Wide receivers
Seniors
1. Corey Davis, Western Michigan
2. Josh Reynolds, Texas A&M
3. Amara Darboh, Michigan
4. Dede Westbrook, Oklahoma
5. Jehu Chesson, Michigan
Underclassmen
1. Mike Williams, Clemson
2. JuJu Smith-Schuster, USC
3. Isaiah Ford, Virginia Tech
4. Malachi Dupre, LSU
5. Curtis Samuel, Ohio State
Reynolds (6-foot-4, 200 pounds) is a steady wideout who has produced for the Aggies. He had 13 touchdowns as a sophomore in 2014. Westbrook had a massive game in the Sooners' win over Texas, as he set the school's single-game receiving yards record with 232. The speedy junior-college transfer (6-foot-0, 175 pounds) had three touchdowns and couldn't be covered.
Tight ends
Seniors
1. Jake Butt, Michigan
2. O.J. Howard, Alabama
3. Jeremy Sprinkle, Arkansas
4. Evan Engram, Mississippi
5. Jordan Leggett, Clemson
Underclassmen
1. Bucky Hodges, Virginia Tech
2. Troy Fumagalli, Wisconsin
3. Tyler Conklin, Central Michigan
4. DeAndre Goolsby, Florida
5. Cam Serigne, Wake Forest
No new names here, but keep an eye on the tweener Engram (6-foot-3, 227 pounds). He leads the Rebels in catches (30), receiving yards (479) and touchdowns (four).
Offensive tackles
Seniors
1. Adam Bisnowaty, Pitt
2. Chad Wheeler, USC
3. Conor McDermott, UCLA
4. Avery Gennesy, Texas A&M
5. Zach Banner, USC
Underclassmen
1. Cam Robinson, Alabama
2. *Orlando Brown, Oklahoma
3. Mike McGlinchey, Notre Dame
4. Roderick Johnson, Florida State
5. Tyrell Crosby, Oregon
The massive Brown (6-foot-8, 340 pounds) might have to move to right tackle in the NFL, but he has impressive feet for a man of his size. And he's just a third-year sophomore. Crosby is out for the season because of a foot injury.
Offensive guards
Seniors
1. Dan Feeney, Indiana
2. Forrest Lamp, Western Kentucky
3. Dorian Johnson, Pitt
4. Nico Siragusa, San Diego State
5. Greg Pyke, Georgia
Underclassmen
1. *Quenton Nelson, Notre Dame
2. Damien Mama, USC
3. Billy Price, Ohio State
4. Sean Welsh, Iowa
5. Tyrone Crowder, Clemson
I wrote about Siragusa on Monday. I think he's a late Day 2, early Day 3 guy at this point.
Centers
Seniors
1. Ethan Pocic, LSU
2. Pat Elflein, Ohio State
3. Jon Toth, Kentucky
4. Tyler Orlosky, West Virginia
5. Cameron Tom, So. Mississippi
Underclassmen
1. Mason Cole, Michigan
2. Frank Ragnow, Arkansas

5. Isaac Rochell, Notre Dame
Underclassmen
1. Myles Garrett, Texas A&M
2. Derek Barnett, Tennessee
3. Charles Harris, Missouri
4. Carl Lawson, Auburn
5. Tyquan Lewis, Ohio State
Hall is a rangy defensive end (6-foot-6, 270 pounds) who might even be able to play outside linebacker in a 3-4. How good are those Texas A&M ends? Charlton (6-foot-6, 272 pounds) is steady, not spectacular, for the Wolverines. He has 13.0 career sacks.
Defensive tackles
Seniors
1. Carlos Watkins, Clemson
2. Chris Wormley, Michigan
3. Montravius Adams, Auburn
4. Jake Replogle, Purdue
5. Ryan Glasgow, Michigan
Underclassmen
1. Malik McDowell, Michigan State
2. Elijah Qualls, Washington
3. Davon Godchaux, LSU
4. Nazair Jones, North Carolina
5. Caleb Brantley, Florida
Qualls is now in my Big Board. Godchaux is a guy to keep an eye on too.
Inside linebackers
Seniors
1. Reuben Foster, Alabama
2. Kendell Beckwith, LSU
3. Keith Kelsey, Louisville
4. Hardy Nickerson, Illinois
5. Ben Boulware, Clemson
Underclassmen
1. Raekwon McMillan, Ohio State
2. Zach Cunningham, Vanderbilt
3. Azeem Victor, Washington
4. Shaun Dion Hamilton, Alabama
5. Anthony Walker, Northwestern
The Cal transfer Nickerson (6-foot-1, 230 pounds) -- yes, the son of that Hardy Nickerson -- is a tackling machine. Victor is a big hitter on the impressive Huskies defense.
Outside linebackers
Seniors
1. Tim Williams, Alabama
2. Jarrad Davis, Florida
3. Jalen Reeves-Maybin, Tennessee
4. Ryan Anderson, Alabama
5. Steven Taylor, Houston
Underclassmen
1. T.J. Watt, Wisconsin
2. Ogbonnia Okoronkwo, Oklahoma
3. Marquis Haynes, Mississippi
4. Elijah Lee, Kansas State
5. Mike McCray, Michigan
Okoronkwo is a fierce pass-rusher with 5.0 sacks for the Sooners. This is his first season with extended defensive snaps.
Cornerbacks
Seniors
1. Cordrea Tankersley, Clemson
2. Tre'Davious White, LSU
3. Jourdan Lewis, Michigan
4. Desmond King, Iowa
5. Damontae Kazee, San Diego State
Underclassmen
1. *Marlon Humphrey, Alabama
2. Teez Tabor, Florida
3. Sidney Jones, Washington
4. Quincy Wilson, Florida
5. Gareon Conley, Ohio State
Just one new addition here, and that's Wilson. Florida has some dynamic cornerbacks. Wilson has five career interceptions, including two this season.
Safeties
Seniors
1. Marcus Maye, Florida
2. Chidobe Awuzie, Colorado
3. Justin Evans, Texas A&M
4. Josh Harvey-Clemons, Louisville

Underclassmen
1. *Jabrill Peppers, Michigan
2. Jamal Adams, LSU
3. *Malik Hooker, Ohio State
4. Donovan Wilson, Texas A&M
5. Marcus Williams, Utah
Hooker, newly added to my Big Board, is a ballhawk with limited experience. Evans, a junior-college transfer, is one of the leaders of a much-improved A&M defense.
Kickers
Seniors
1. Jake Elliott, Memphis
2. Zane Gonzalez, Arizona State
3. Conrad Ukropina, Stanford
4. Bobby Puyol, Connecticut
5. Andy Phillips, Utah
Underclassmen
1. Daniel Carlson, Auburn

Barnes has missed only two kicks this season.
Punters
Seniors
1. Justin Vogel, Miami (Fla.)

Hunt is a four-year starter with a big leg.
