I am afraid Billy Sastard hit the nail on the head.  Some guys do well in practice but can't make the quick decisions in the game.  Lynch even struggles with decisions in practice.  It looks like he didn't do enough work in the offseason.  He doesn't understand how hard he has to work to be a starter in the NFL.  Hopefully losing the job this year will get him to find a new level in his study habits.  If he doesn't come back next year and wow them right out of the box next year he will be cut in training camp.
