Favre never looks to run he is always looking to pass. That's not the problem, he just makes to many dumb decisions when he does pass.
The only game I can recall where we went all out pass as a game plan was against 'zona. (I missed the st. louis game). We put up 35 pts in a half. Berfore that and ever since, we have not gone 4 and 5 wide regularly the whole game. Why the hell not?
