I don't think it is Hack's confidence that is hurting him as much as it is his going into safe mode to protect his NFL draft stock. It is like he and his family had a discussion prior to the season to say, if they aren't blocking, don't risk it. Get down and protect the millions coming.
Well, Hack is losing a ton of money if he continues to play like a Sally. What GM wants to go first round on a rocket arm with a pansy heart? What franchise wants a QB that refuses to throw the ball away if nothing is there and no time is left?
Hack has become the anti-Michael Robinson, who won and lead because he played with everything he had and left it all on the field, and maybe delivered too many of his own hits for a QB. Heck, even Kerry Collins came out and ran over a dude at the start of '94. It's sets a tone and so does covering up in the face of any pressure. We need Hack to grow a pair and realize that if he doesn't start playing instead of managing risk, his stock will continue to freefall.
