As I recall, Spriggs didn't look as bad last year (as a rookie, no less) as he does this current one. Something happened to him in the off-season that really got into his head. We really couldn't see much when the OTAs began, but from the first pre-season game, it was evident he was lost. and he has regressed even further from that point.
I want to believe it's something he can overcome, but if he is as bad at the opening of next year, I hope they don't keep him around like they did Newhouse.
