Predicting college football is hard enough.

When it comes to prognostications, some players and the uncertainties surrounding them make life much more difficult. For some it’s injuries. For others it’s off-the-field troubles or just under-performing. Whatever the reason, certain players seem to leave coaches and fans scratching their heads in doubt.

Here’s a look at 10 unpredictable players that we’re not quite sure what to make of yet this season in the SEC:

Alex Anzalone: Florida, LB

One of the more-hyped players to arrive in Gainesville the last few years, LB Alex Anzalone has widely underachieved with the Gators registering 16 tackles and one tackle for loss in just eight career games. The junior likely will get a chance to prove himself early this season as Antonio Morrison continues to recover from knee surgery. A shoulder injury relegating Anzalone to special teams and just two games as a freshman. Now an upperclassman, Anzalone is running out of time to live up to the potential that made him one of the most sought-after inside linebackers in the nation out of high school.

Dorian Baker: Kentucky, WR

Dorian Baker has all the tools to be Kentucky’s next great wide receiver. But off-the-field issues have plagued the rising sophomore, including citations for bar fights and shooting pellet guns on campus. In eight games last year as a frosh, Baker hauled in 19 passes for 199 yards and a touchdown. Baker has a real chance to be a star with Patrick Towles under center the Wildcats. Along with fellow sophomore Blake Bone, Towles has a pair of talented weapons in which to post top-five passing numbers once again in the SEC.

Daeshon Hall: Texas A&M, DL

Daeshon Hall lost his starting role after four games last season, but still managed to tally 29 tackles, 4.5 sacks and 6.0 tackles for loss. The Aggies rushing defense was porous at best in 2014, meaning Hall will be asked to step up and fill some gaps. Julien Obioha has moved to defensive tackle, so Hall will line up opposite Myles Garrett to rush the passer. Hall was highly recruited out of Lancaster, Texas, but whether he can step up as a leader on the Aggies defense remains to be seen.

Brandon Harris: LSU, QB

Brandon Harris appears to the have the slight edge over Anthony Jennings for the LSU starting quarterback role, even though Les Miles isn’t budging an ounce on naming the Tigers’ starter after the team’s second scrimmage. Harris didn’t exactly blow anyone’s skirt up last season in the eight games he played under center. He finished with 452 yards passing to go along with 6 touchdowns and 2 interceptions. A year under his belt, however, should do wonders for his maturity and experience level. If he can beat out Jennings, Harris has a chance to lead a Tigers team that can challenge for the SEC West title.

C.J. Johnson: Ole Miss, LB

C.J. Johnson was a beast at defensive end with 4 sacks and 8 TFLs. Now the Rebels are hoping he can replicate that production at the MIKE linebacker position. The senior makes the move this year to provide depth along the Ole Miss defensive front. With Marquis Haynes and Fadol Brown manning a fairly deep defensive line, Ole Miss head coach Hugh Freeze was able to move Johnson to linebacker, a position at which the Rebels previously were thin. So far so good as the Butkus Award for the nation’s top linebacker already has added Johnson to its preseason watch list.

Keith Marshall: Georgia, RB

To say the Georgia Bulldogs are stacked at running back would be an understatement with Nick Chubb and Sony Michel returning to Athens with a combined 1,957 rushing yards last season. If Keith Marshall can overcome the injuries (torn ACL, hamstring) that have sidelined him the last two seasons, then Georgia has the potential to enter the season with a trio of talented backs. Marshall has 1,029 yard and 9 TDs in his career, but hasn’t has more than 60 carries in a season since his freshman campaign when he rushed for 759 yards and all but one of his career touchdowns.

Maty Mauk: Missouri, QB

It’s funny how a player who has led the Tigers to consecutive SEC East titles enters the season still highly unpredictable. But that’s Maty Mauk, the venerable leader of the Missouri offense. Mauk tossed for 2,648 yards 25 touchdowns last season, but troubles with accuracy continues to plague the rising junior. Mauk makes up for it with his legs, his grit and leadership skills. It’s hard to knock a guy who’s won two straight divisional titles, but if Mauk’s struggles with inaccuracy continue, teams like Georgia or Tennessee could swoop in and steal the SEC East.

Marquez North: Tennessee, WR

If Marquez North can stay healthy, the Tennessee offense could be a force to be reckoned with come this fall. That’s proven to be a challenge. The junior has been besieged by injuries, including an ailing leg that forced him to miss time this summer. The former four-star recruit hauled in 320 yards and 4 touchdowns last season. If North can step up, he’ll join a deep roster of wideouts, led by Pig Howard, Von Pearson and Jason Croom. If healthy, North can be just as good, if not better, than all of them.

Armani Watts: Texas A&M, S

Armani Watts has the potential to be among the top defensive backs in the SEC. He burst onto the scene at Texas A&M last season as a true freshman, racking up 3 interceptions and 55 tackles. But for all the talent and bone-rattling hits, the rising sophomore is a part of an Aggies secondary that was beset by poor tackling and playing out of position. If he can tighten up his fundamentals, the cornerback has a change to be something special. The key will be turning him from a raw talent to a team leader.

Deatrich Wise Jr.: Arkansas, DL

Deatrich Wise Jr. only had 13 tackles last year. But three of them went for a loss, while another two went down on the stat sheet as sacks. The 6-foot-5, 272-pound redshirt junior is the purest pass rusher on Arkansas’ deep defensive line and probably has the most potential. A shoulder injury has slowed Wise this summer, but he’s competing for a starting position at defensive end for the Razorbacks opposite of JaMichael Winston. If he can survive the rigors of a full season, expect big numbers from Wise on a revamped Arkansas defense. A full year for Wise in a prominent role could make for a long season for opposing quarterbacks.
