Players in the Class of 2015 are just getting into the heart of their college careers. That being said, some members of the class have overachieved and improved from where their recruiting stock was.

Here are five players who are well on their way to stardom:

QB Sam Darnold, USC, ESPN 300 ranking: 115

Ricky Town was the anointed QB in USC’s 2015 recruiting class, but Darnold was the better player then and now (yes, we did have Darnold ranked higher). This former two-sport athlete might not have received the hype of others, but that might have aided his development, allowing him to redshirt and grow without any pressure. After a freshman season in which Darnold passed for 3,086 yards and 31 TDs, Darnold has exceeded early expectations, and he could be a No. 1 draft pick one day.

RB Mark Walton, Miami, ESPN 300 ranking: 114

Walton was a late edition to the ESPN 300 for the 2015 class because he re-classified from the 2016 class so he entered college a year early. He has made quite the impact in a short period, rushing for 1,117 yards and 14 scores as a sophomore, and will go into next fall as one of the top backs in college football for Mark Richt’s Hurricanes. If you aren’t all that familiar with him yet, you will be.

DE Clelin Ferrell, Clemson, ESPN 300 ranking: 136

No program has taken moderately rated (not top-100 type) defensive linemen out of high school and made them stars better than Clemson. Ferrell is a future star. His long frame just needed weight and strength to be added so that he wouldn’t only be labeled a pass-rusher, but that still is what he does best. His six sacks in 2016, in a substitute pack, are only scratching the surface of what he’s going to become.

ATH Ray-Ray McCloud, Clemson, ESPN 300 ranking: 157

McCloud was so tough to project coming out of high school. He played exclusively as a RB in a run-heavy, I-formation scheme, but was undersized as a true back. Every camp he attended he worked out with the wide receivers and had terrific ball skills, but rarely played receiver in a game. His role with Clemson is much more befitting his skill-set. He’s a utility weapon that can do a little bit of everything, including playing RB if need be as a change of pace.

ATH Jauan Jennings, Tennessee, ESPN 300 ranking: 190

He was lightly recruited as a dual-threat QB, but in all reality everyone projected him as a safety or wide receiver. Jennings just needed to realize it and it didn’t take long once he arrived in Knoxville. He surprisingly played quickly and has adapted further ahead of schedule than expected to the little nuances of playing wide receiver full time. He’s a terrific athlete who will only continue to get better and is a natural playmaker.

One who has underachieved

DE Byron Cowart, Auburn, ESPN 300 ranking: 1

Cowart has yet to make his mark at Auburn. In two seasons spanning 23 games at defensive end, the former Under Armour All-America Game MVP has totaled just 12 tackles without a sack. He wasn't able to bring the immediate pass-rush ability and only played sparingly as a freshman. Cowart was then beaten out this season by Marlon Davidson, who made a number of all-SEC freshman and freshman All-American teams.
