When a five-star recruit pledges to an SEC school, he’s expected to make an immediate impact. Georgia QB Jacob Eason, a five-star early enrollee, has already become one of the most talked-about newcomers in college football.

Freshmen contributors are not restricted to five-star signees, look no further than the SEC East’s own Antonio Callaway, a three-star prospect in 2015 who played a key role in Florida’s 7-1 conference campaign to claim the division title last fall.

Which non five-star recruits, according to 247Sports composite, could have a similar impact this season?

Tyrie Cleveland, WR, Florida: Since the Gators last played in the Citrus Bowl, Demarcus Robinson has been drafted by the Kansas City Chiefs and Callaway has been indefinitely suspended. In spring practice, various receivers drew praise from the coaches, but no one locked up a starting job, setting up an opportunity for Cleveland to be a first-stringer early in the fall.

Cleveland has the height (6-3) and agility to be a threat from anywhere on the field, but the question will be if enrolling in Summer B gives him enough time to climb the depth chart at a relatively deep position. Jim McElwain and Doug Nussmeier’s scheme has proven effective at getting wide receivers open. Will Cleveland get the routes down in his rookie season?

Jeff George, WR, Tennessee: With Josh Dobbs as signal-caller, the play is never truly over until the whistle blows. Dobbs’ scrambling abilities and knack for improvisation has led to some highlight runs, but with George on the field the Tennessee quarterback might feel more comfortable lobbing jump balls.

George, a junior college transfer, stands 6-foot-6 and displayed impressive athleticism in UT’s spring game. His attributes and Tennessee’s offense should be a potent combination.

Brandon McIlwain, QB, South Carolina: The Gamecocks have a new coach, new play-caller, and in all likelihood, a new quarterback. Last season’s Week 1 starter Connor Mitch has opted to transfer, and while Perry Orth or Lorenzo Nunez could win the starting job again, most of the buzz surrounds McIlwain.

As an early enrollee, McIlwain has a leg up on the recently reclassified Jake Bentley. McIlwain’s skills appear to be a perfect match for offensive coordinator Kurt Roper’s spread-based system.

Landon Young, OT, Kentucky: The highest-rated signee of UK’s 2016 class is in a position group that struggled mightily last year. Young’s listed measurements of 6-foot-7, 270 pounds are not ready for the trenches of the SEC, but he has plenty of time to put on weight. Kentucky coach Mark Stoops identified Young as a possible starter in February.

“I think Landon is most definitely one of the more talented true freshmen I’ve been around in any school,” Stoops told 247Sports. “He has great upside. He’s a worker, humble, wants to play. I think he has a good chance.”

If Young can bulk up, there should be a spot for him somewhere on the UK offensive line.

Joejuan Williams, CB, Vanderbilt: Williams was ruled ineligible for the 2015 high school season due to not transferring far enough from his former school, but that didn’t stop from gaining a four-star rating and multiple SEC offers. As an early enrollee, Williams took part in spring practice with the Commodores, helping make up for the lost 2015 season.

Vanderbilt’s defense has been a strong suit during the Derek Mason era, but there’s room for improvement in the turnover department. Williams’ knack for picks and pass breakups could be a boost in the secondary in 2016.
