Fall practice starts in less than two weeks, it’s finally here! We’re counting down to kickoff using content-specific pieces every weekend to deliver the good stuff — last-minute primer involving all 14 SEC teams.

Up next: Introducing the league’s most valuable backups, athletes who will be vital to their respective team’s success:

Six backups who will shine in 2015

Treon Harris, Florida, QB, Sophomore — Jim McElwain hasn’t yet named Florida’s starting quarterback, but redshirt freshman Will Grier had the obvious edge coming out of fall practice and the Gators’ coach said as much when pressed on the issue. Of course Harris is the kid with the experience having played well in spurts during Jeff Driskel’s periods of inconsistency last fall. Grier might be the more talented option from a passing standpoint, but Harris can get the Gators out of trouble on third down and they’ll need his freelance ability considering the offensive line will be the SEC’s least experienced.

Daeshon Hall, Texas A&M, DE, Junior — Tall and rangy with a touch of mean, Hall will be a factor within John Chavis’ front seven this fall playing behind senior pass rusher Julien Obioha and standout sophomore Myles Garrett. Hall made five starts as a sophomore and finished the season with 29 tackles, including six behind the line of scrimmage. For the first time in Kevin Sumlin’s tenure, the Aggies appear to have a complete two-deep along the front four. Even as a reserve, Hall will manage at least five sacks this season.

Damien Harris, Alabama, RB, Freshman — The Crimson Tide’s third scholarship running back this fall, a five-star true freshman with a ton of hype, Harris won’t be redshirted considering Alabama’s lack of depth behind Derrick Henry. It’s Kenyan Drake, Harris and that’s it as far as ballcarriers go unless Lane Kiffin’s expecting an unknown to share the rushing load. Groomed to be a premiere player down the road, we’ll see Harris early this season if the Crimson Tide decide to use Drake in a more versatile role in varying formations like the coaching staff has mentioned. Harris didn’t have the luxury of going through spring as an early enrollee but shouldn’t have a problem handling what’s thrown at him playbook-wise in August.

Shy Tuttle, Tennessee, DT, Freshman — We didn’t list five-star freshman Kahlil McKenzie here because he’s probably going to start, so Tuttle in a rotational role up front for the Vols will be vital to Tennessee’s defensive success this season. Curt Maggitt and Derek Barnett coming off the edges and the freshmen 1-2 punch of McKenzie + Tuttle up the middle? Opposing offenses aren’t going to want to dealt with that freak show. Veteran defensive back Cam Sutton spoke highly of both newcomers at SEC Media Days and said he expects Tennessee’s pass rush to be amongst the nation’s best. We’d have to agree based on the personnel.

Chandler Cox, Auburn, FB/TE, Freshman — I watched this guy star locally at several positions last season for Apopka High (near Orlando, Florida), the same program that produced five-star Gators signee Martez Ivey and came away impressed after every outing. He performed well this spring as a lead blocker and option out of the backfield in Auburn’s tempo-based spread and will split time with projected starter Kamryn Pettway at a hybrid fullback-tight end position for Gus Malzahn. At 6-foot-2, 225 pounds, Cox is a freight train of muscle coming through the hole and isn’t afraid to hit — just watch some of his vicious tackles at middle linebacker last fall in the Sunshine State.

Jeremy Sprinkle, Arkansas, TE, Junior — Playing behind preseason watch list-lauded Hunter Henry could be difficult to handle mentally for any player wanting the football, but not Sprinkle, a two-year contributor and essential part of the Razorbacks’ offense. Not only can Sprinkle, a third-year junior, seal the edge when asked from a blocking standpoint, but he’s a 6-foot-6 target downfield with great hands — the ideal complement to Henry. ‘Twin tights’ never looked so good for Bret Bielema and new OC Dan Enos.
