With national signing day in the books, RecruitingNation is looking at the top position classes in each conference. For the full series, click here.

Quarterback

The Florida Gators had a major need at quarterback in the Class of 2014, and Will Muschamp and staff more than filled it, signing two of the nation’s top signal-callers. Third-ranked dual-threat prospect Will Grier (Davidson, N.C./Davidson Day School) is already on campus and preparing for spring practice, while No. 7 dual-threat prospect Treon Harris (Miami/Booker T. Washington) was a huge signing-day flip from Florida State. Both prospects are great athletes who are accustomed to operating uptempo offenses. This should also help newly hired offensive coordinator Kurt Roper, who will install a similar scheme in Gainesville.

Running back

Tennessee went into the 2014 class with a gigantic future need at running back, and coach Butch Jones and staff delivered for Volunteers fans in a big way. The Vols' running back haul includes not only ESPN 300 backs Jalen Hurd (Hendersonville, Tenn./Beech) and Derrell Scott (Havelock, N.C./Havelock) but also four-star Treyvon Paulk (Alpharetta, Ga./Milton). With different body types, styles and strengths, Tennessee added talent and depth for years to come as well as many different skill sets within the position. Hurd is tall, lean and chock-full of speed, athleticism and versatility, and Scott is a slasher with excellent ball skills out of the backfield. Paulk is a compact, downhill back with leg drive and power.

Tight end

South Carolina knocked out needs at cornerback and on the defensive front, and the Gamecocks also picked up two tight ends in ESPN 300, No. 143 Kevin Crosby (Bamberg, S.C./Bamberg-Ehrhardt) and high three-star Kalan Ritchie (Goose Creek, S.C./Goose Creek). They're each a different type of player for Steve Spurrier and his staff. Crosby is a tight end who projects as an H-back, while Ritchie is an in-line blocking prospect who needs time to develop physically and refine his technique.

Wide receiver

While the Baylor Bears had an exceptional wide receiver class, the nod here goes to LSU. Not only did the Tigers sign the nation's No. 1 receiver in Malachi Dupre (River Ridge, La./John Curtis Christian), but also the No. 3 ranked receiver in Trey Quinn (Lake Charles, La./Barbe) and ESPN 300 No. 271 D.J. Chark (Alexandria, La./Alexandria Senior) and No. 283 Tony Upchurch (Pearland, Texas/Dawson). In Dupre, LSU snagged the No. 17 prospect overall on signing day. He has a tall, lengthy frame with a near ideal size-and-speed combination and elite high-point ball skills. Quinn will enter LSU as an advanced route-runner with separation skills and the ability to pluck the ball outside of the framework of his body. Chark brings initial quickness and the vertical speed to take the top off a defense, and Upchurch is a big body who continues to add bulk and could eventually transition to a flex type of position.

Offensive line

Not only did Alabama put together the best offensive line class in the 2014 cycle, but it's also one of the best in recent memory. The Crimson Tide inked early enrollee and five-star offensive tackle Cameron Robinson (Monroe, La./West Monroe) and also got top-ranked junior college offensive tackle Dominick Jackson (San Mateo, Calif./College of San Mateo). On the interior, the nation's top two centers, No. 168 overall Josh Casher (Mobile, Ala./Saint Paul’s Episcopal) and No. 190 J.C. Hassenauer (Woodbury, Minn./East Ridge) signed, as did No. 3 guard Ross Pierschbacher (Cedar Falls, Iowa/Cedar Falls). A second guard in the class is three-star Montel McBride (Plant City, Fla./Plant City), who could also play nose tackle at the next level.

Defensive line

Texas A&M went into the 2014 class knowing that size and athleticism was an absolute must on its defensive front. And Kevin Sumlin and staff delivered on those glaring needs. Leading the way is No. 1 defensive end and five-star player Myles Garrett (Arlington, Texas/Martin), who has the size, speed and power combination to be a difference-maker early on next fall. The 6-foot-5, 247-pound Garrett is joined at defensive end by ESPN 300 No. 203 Qualen Cunningham (Chandler, Ariz./Hamilton), and high three-star Jarrett Johnson (Katy, Texas/Seven Lakes), who has a nonstop motor. While the Aggies have some talented young defensive tackles, continuing to add size and athleticism to the interior was a must. No. 150 DeShawn Washington (Nederland, Texas/Nederland) and four-star early enrollee Zaycoven Henderson (Longview, Texas/Longview) add disruptive explosiveness and athleticism.

Defensive backs

The top class of defensive backs goes to Alabama, by a landslide. While the Crimson Tide have provided many recruiting firsts in recent years under coach Nick Saban, the 2014 class is the first to have two five-star cornerbacks in the same cycle in the years ESPN has been assigning star rankings. No. 8 overall Tony Brown (Beaumont, Texas/Ozen) and No. 15 Marlon Humphrey (Hoover, Ala./Hoover) have the size and speed that Saban and his staff made a must in 2014. Add in No. 3 safety and No. 27 overall Laurence Jones (Monroe, La./Neville) and Alabama signed three of the very best at defensive back. Factor in that No. 7 athlete Ronnie Clark (Calera, Ala./Calera) seems destined to begin his career at safety and the Crimson Tide dominate in the secondary despite having missed out on coveted safety target C.J. Hampton (Meridian, Miss./Meridian).

Linebackers

The Alabama Crimson Tide’s 2014 class fill just about every need on the board, and that includes linebacker. With designs on addressing pass rushing and the ability to play in space on the edge at outside 'backer in Nick Saban’s 3-4 scheme, Alabama signed the Nos. 1 and No. 2 outside linebackers in the country in No. 48 overall Christian Miller (Columbia, S.C./Spring Valley) and No. 52 overall Rashaan Evans (Auburn, Ala./Auburn), who is pound for pound of the best pure athletes in the 2014 cycle. The Crimson Tide added two more talented linebackers in ESPN 300’s No. 102 Shaun Dion Hamilton (Montgomery, Ala./Carver) and No. 281 Keith Holcombe (Tuscaloosa, Ala./Hillcrest). Hamilton is an MLB.

Athletes

Texas A&M signed a number of talented athletes in the 2014 class, including five-star Speedy Noil (New Orleans/Edna Karr). The quick and elusive Noil is already enrolled and will play slot wide receiver and return punts and kicks. Joining Noil in College Station will be ESPN 300 No. 61 Nick Harvey (Richmond, Texas/Travis), who could play cornerback, nickel or safety, and No. 251 Armani Watts (Forney, Texas/North Forney). A fourth athlete in the class is three-star senior riser Donovan Wilson (Shreveport, La./Woodlawn), who, like Watts, will play defensive back.
