GAINESVILLE, Fla. -- Florida's offense has been a problem for a few years now, and the line has taken its fair share of the blame. But 2013 was supposed to be different.

The O-line was expected to key a resurgent offense last season. It was experienced, talented and deep. But like a lot of positions on that woeful 2013 offense, a few injuries led to wholesale collapse.

To make matters worse, three senior starters departed and a key reserve was among three transfers. When the dust settled, Florida had just nine offensive linemen on scholarship.

Last Wednesday, coach Will Muschamp announced a recruiting class with six offensive linemen, including three who are already on campus as early enrollees.

"We're getting our numbers back on the offensive line," Muschamp said. "We're right at 15. You'd like to have 15 to 17 offensive linemen on scholarship. That's a developmental game, but that's a huge developmental position, and that's where you've got to have guys in your program. So it's good to see that."

The offensive line continues our week-long series of the Gators' top positions with room to improve.

Battling for No. 1: It's not hard to project UF's starting offensive line because only five linemen on the roster have ever started a game. Only seven have ever played in a collegiate game, so there is a strong likelihood that those five veterans will be the Gators' starters. D.J. Humphries will look to reassert himself at left tackle after an injury-plagued sophomore season. Max Garcia should slide back to the left guard spot he played last season before injuries forced him to shuffle. Chaz Green, who started 19 games in two seasons, returns after missing last season due to injury. He mostly played right tackle but lacks bulk and could move inside. That would allow Florida to stick with 6-foot-8, 361-pound Trenton Brown on the outside. Then there's 6-5, 320-pound Tyler Moore, who played mostly at tackle last season before breaking his elbow. He could be a prime candidate to take over at center.

Strength in numbers: Florida hasn't developed much depth in recent years, and several offensive linemen have left the program. Trip Thurman, who will be a fourth-year junior this fall, has all of 15 career games as a backup under his belt. But that might make him the Gators' top reserve. Much was expected of Octavius Jackson, who came the closest to burning his redshirt last fall as a standout on the scout team. But his hometown newspaper recently reported that a shoulder injury has ended his playing career. Florida's other two linemen who redshirted last season will be counted on as key reserves in 2014. Roderick Johnson is well-built at 6-5, 316 pounds and could play tackle or guard. And Cameron Dillard was recruited as UF's center of the future. He'll need time to develop, however, because center is such an important position that it's doubtful the Gators would throw an untested freshman into the fire.

New on the scene: Of Florida's six new O-linemen, juco transfer Drew Sarvary might have the best chance of securing a role on the two-deep roster because he started 10 of 11 games for Florida A&M as a freshman before heading to junior college. The next most likely is guard Nolan Kelleher, who enrolled early and has the size (6-6, 305) to play right away. Another early enrollee, tackle Kavaris Harkless, will need time to bulk up. That and raw technique are common issues with true freshman offensive lineman, so it will take a special effort for any of the three freshmen who arrive this summer -- David Sharpe, Travaris Dorsey and Andrew Mike -- to earn significant playing time in the fall. Sharpe, the No. 2 OT prospect in the Class of 2014, has the athleticism to shine. Dorsey (6-3, 314) and Mike (6-6, 278) have the size to surprise.
