Tressel is human but saying he will make mistakes with his selection of recruits is speculative. In Ohio he has one of the best pools of talented kids to select from and those that were selected just happen to have the right mix of "stuff" to impress JT. There may be better players all over the country that he will never see except for maybe on the football field playing tOSU. It's my humble opinion that a great coach will take a collection of talented kids and make them into a winning football team. No one player will take them to undefeated status or the playoff games. But one coach with his collection of talented 3 and 4 star players will. Tressel made no mistakes, he knows what he's doing for the team. He, after all, is the Mastermind.
