Tony Romo, much like Brett Favre was, is a dumbass with big time playmaking ability.
Mike Holmgren was able to reel Favre in early on, and won a SB, but his dumbassery through the following years cost the Packers further opportunities.
Romo's playmaking keeps the Cowboys competitive, but his dumbassery costs them equally.
I'd be no more happy to have traded for him than I am with Alex Smith.
The only real question, how do you want to lose your playoff games?
