Technically speaking, every college football recruit in the 2015 class has the potential to turn a program around.
High school players are pure potential energy, as evidenced by overlooked recruits like Khalil Mack, who broke records at Buffalo and went No. 5 overall in the 2014 NFL draft.
But recruiting services get better and more accurate every year. The process is far from (and never will be) infallible, but for the most part the players with the greatest program-transforming potential are ranked at or near the top of the class.
Still, in putting together this list, I attempted not to go all chalk. It would be useless just to rank the top player at each position on the 247Sports Composite. You could do that yourself.
Instead I picked through the top 60 or so prospects, noting players with considerable upside. Some may not rank as high because of current polish, production or physique, but with the physical tools they possess, the right system could turn them into impact players.
For the most part, I also tried to vary the positions.
For example, the top quarterbacks will all be counted on to change their respective programs, but I highlighted the one with the highest ceiling (in my opinion).
Let's get started.
