GAINESVILLE, Fla. -- With a 15-player senior class and seven players transferring or leaving since the end of the season, Florida has plenty of holes to fill.

Considering all seven of those departing players were from the offensive side of the ball, it's obvious where much of the Gators' recruiting efforts are focused.

Florida has 23 scholarships available with cornerback Louchiez Purifoy forgoing his senior season to enter the NFL draft.

Here's a breakdown of Florida's biggest needs in restocking its roster with talent.

Quarterback: The Gators have a starter in Jeff Driskel, who is expected to recover from a broken bone in his lower leg that required surgery. Their most experienced backup, Tyler Murphy, surprised the coaching staff when he decided to transfer, but Skyler Mornhinweg remains. He started UF's last three games of the season as a redshirt freshman, but it remains to be seen how Mornhinweg will fit into Florida's new offense.

The numbers are obviously low with just two scholarship QBs on the roster, but help is on the way. Florida expects Will Grier, the nation's No. 2-ranked quarterback, to enroll in early January. Now that Murphy has departed, expect the Gators to add a second quarterback to their 2014 class. A dual-threat QB who can bring a more athletic dimension and schematic flexibility to the position makes the most sense. Coach Will Muschamp will let his new offensive coordinator find the right fit.

Offensive line: Florida graduated three starters and lost reserve Ian Silberman to transfer along with two others who were buried at the bottom of the depth chart. That's six departures -- a lot for any season. Muschamp likes to have at least 15 offensive linemen on his roster, so expect a handful of newcomers. Offensive line has been a sore spot for the last two seasons, and injuries decimated Florida in 2013. The Gators return five players with starting experience, but depth must be created as only four other scholarship linemen remain. With so few bodies, at least one of the incoming prospects can expect to make the two-deep roster.

Florida needs the most help on the edges, which is why the headline OL commitment is David Sharpe, the nation's No. 2-ranked offensive tackle prospect. The Gators recently signed Drew Sarvary, a 6-foot-6, 310-pound juco OT who could also play inside. Of all the newcomers, he'll have the inside track to play first. Florida also has pledges from three of the nation's top-30 guard prospects in Nolan Kelleher (6-5, 310), Travaris Dorsey (6-3, 314) and Dontae Angus (6-5, 310).

Offensive skill positions: Florida's QBs haven't had much time to develop in the passing game in recent years, and some of the blame can be directed at the offensive line. But nothing is more obviously missing in the Gator offense than playmakers at the wide receiver and tight end positions. The Class of 2013 saw five talented freshmen WRs join the program, three of whom saw action. But with two senior starters leaving, it's imperative that UF continue to add talent and numbers to its receiving corps. The Gators' top wide receiver commit for 2014 is Ermon Lane, the No. 2 WR prospect in the country. Keeping him in the fold is a top priority.

UF also has pledges from former FSU commit Ryan Sousa and Moral Stephens. At 6-3 and 200 pounds, Stephens would give UF a prospect with some size who could play H-back or grow into a full-time role at tight end. Florida has just three scholarship TEs on its roster, but has commitments from DeAndre Goolsby and C'yontai Lewis, both three-star prospects. The Gators have plenty of talented options returning at tailback but lack a game-breaking home-run hitter who can gain the edge. That's why it's so important they hang onto the commitment of Dalvin Cook, the nation's No. 4 RB prospect. Coaches presume he would have a role as a true freshman in 2014.

Defensive line: Florida is in good shape with 10 returning scholarship players. But Muschamp's multiple-scheme defense, which uses 4-3 and 3-4 alignments up front, puts a heavy emphasis on defensive linemen making plays and disrupting the opponent's offense. Florida has three commitments -- DT Khairi Clark, DE Taven Bryan and DE Justus Reed. Bryan could end up on offense, so the object of much of Muschamp's hard work on the recruiting trail is adding another difference-maker who can rush the passer.

Cornerback: The Gators graduated two cornerbacks and are losing Purifoy to the NFL. If he is joined by fellow starter Marcus Roberson, who is projected as a first-round pick in ESPN Insider Todd McShay's first mock draft, there will likely be immediate playing time available. That's Muschamp's sales pitch. It's also why Florida is trying to load up on DB prospects. The nation's No. 10 athlete, J.C. Jackson, is committed, as are Chris Lammons, Quincy Wilson and Duke Dawson. Wilson and Dawson could end up at safety, so Florida must close strong in adding at least one more pure cornerback with the talent to contribute right away. Florida hit the jackpot last year in signing All-SEC first-team CB Vernon Hargreaves III. Few prospects enter the college ranks as technically skilled and prepared as he, but the Gators are hoping another recruiting bounty will keep the pipeline of impact cornerbacks flowing.
