What may concern you: Despite making a lot of big plays last season, Mayes is not a burner. Sure, his 5.0/40 time at a Nike Camp before his junior season isn't a real good indicator of his true speed, but he's probably a legit 4.7 kid on the field right now. And with that said, he's more of a free safety prospect. Often times when you have kids with less than ideal speed in the secondary, they often play up as the strong safety. Mayes still needs to prove that he can play up in the box and make a lot of plays. And now that he's at Northwestern High in Miami, it'll be interesting to see if he can continue putting up big numbers that we saw from him in flashes last season.
Bottom Line: Mayes has plus size, tremendous leaping ability, excellent ball skills, and the ability to do some things with the ball in his hands in the open field (possibly indicating a future in the return game). He seems to have the intangibles you look for. However, he needs to become a more physical player at the position and he lacks ideal speed for a free safety. Mayes had just one other BCS offer, from Syracuse, so he was recruited like a high 2/low 3 star prospect. He grew up a Miami fan so getting more offers later likely won't matter to him. He is Miami's first safety commit in the Class of 2014. They will likely sign one more at the position.
