The transition from high school to college is a major adjustment for college true freshmen. The transition from high school to the SEC is a whole other animal. Still with opening day in the SEC upon us, there are 11 true freshmen that are listed as starters on SEC depth charts. That number is sure to grow as the season progresses. Below we break down the select few opening day true freshman starters in the SEC.

Cameron Robinson is quickly living up to his top tackle billing.

Freshmen are listed in order of their 247Sports Composite rank in the 2015 class.

Cameron Robinson, Alabama, LT – (247Sports Composite No. 1 OT) The top offensive tackle in the country is supposed to be different than your average true freshman. By winning the starting left tackle job on a national title contender, Robinson is already living up to his ‘franchise’ rating of 100 on 247Sports.

Speedy Noil, Texas A&M, WR – (247Sports Composite No. 1 WR) We’ve been looking for the next Percy Harvin since Percy Harvin and we may have finally found him in Noil. After making splash plays throughout the spring and preseason, Noil is giving Aggie fans reason to believe that the explosive A&M offense will have different faces but the same results.

Brandon Harris, LSU, QB – (247Sports Composite No. 3 Dual-threat QB) Harris is listed as a co-starter alongside Anthony Jennings at LSU but the expectation is that the job will ultimately be the true freshman’s in Baton Rouge. Though he’s athletic, Harris has quickly developed a reputation as having one of the most lively arms in the nation for his class.

Derek Barnett, Tennessee, DE – (247Sports Composite No. 11 strongside DE) It isn’t the athleticism that has been drawing praise for Barnett in Knoxville (though he’s got plenty of it). It’s his motor. That motor and work ethic has quickly moved Barnett into a starting role at Tennessee and that was evident in high school as a two-way player at Brentwood Academy. There was some speculation that Barnett could eventually end up at defensive tackle but he’s looking perfectly comfortable on the outside.

Armani Watts, Texas A&M, S – (247Sports Composite No. 19 S) Rated a four-star prospect by the industry, Watts was highly regarded by our team at 247Sports as the No. 12 safety in the country. Though he’s not a towering physical presence, the kid just made plays and had a great feel for the position. He beat out incumbent starter Floyd Raven to win the job in College Station.

Boom Williams, Kentucky, KR - (247Sports Composite No. 5 all-purpose back) For an explosive, dynamic athlete that can make plays with the ball in his hands, the return game is a great place to throw a true freshman into the shallow end of the pool. Williams is going to get a chance to make an immediate impact with the ball in his hands without having a mastery of the playbook.

Evan Berry, Tennessee, KR – (247Sports Composite No. 22 ATH) Though he hasn’t found a starting job in a positional role, Berry is too athletic not to find the field at Tennessee immediately and Butch Jones has inserted the legacy freshman into a kick returner’s role.

Isaiah McKenzie, Georgia, PR – (247Sports Composite No. 50 WR) 247Sports saw McKenzie significantly higher than the rest of the industry and his value in the return game is why. Nicknamed ‘joystick’ in high school, McKenzie is making an immediate impact as a returner and he’ll be sure to give us a few highlights this season. (307)

Ethan Wolf, Tennessee, TE – (247Sports Composite No. 14 TE) Part of a pair of highly-touted tight ends to sign with Tennessee in 2015, Wolf was actually the lower rated of the two behind Daniel Helm. However he was also the bigger, more physically prepared of the two and he’ll have an opportunity to catch passes immediately for the Vols in Knoxville.

Jashon Robertson, Tennessee, OG – (247Sports Composite No. 40 OG) Though Vanderbilt and then Tennessee recruited and committed Robertson as a defensive tackle, he was always ranked as an offensive guard on 247Sports because that’s where we felt he best projected. That has quickly panned out as Robertson’s wrestling background, toughness and smarts have made him an immediate starter only weeks after switching positions.

Al Harris, South Carolina, CB – (247Sports Composite No. 43 CB) Though Harris may not have been anyone’s first pick to be an early contributor based strictly on rating or frame (he’s only 160+ pounds), no one should be surprised that Harris has won a job. He came to South Carolina polished, he has NFL pedigree and St. Thomas Aquinas in south Florida has been regularly putting out instant contributors in college. (628)
