Flacco protects the ball, but if you look at his stats they are far from extraordinary.
Besides, Baltimore has a solid Running game, that takes loads of pressure form Flacco.
He's performed well when he needed to, but he hasn't done much past that.
Tony has a turnover problem, but it's partly due to an overrated Offensive line. BIGG and Gurode are really the only solid linemen, Flo commits way too many penalties and is getting old, LG is an issue (We need a solid lineman at the spot), and Colombo is alright, but he's not outstanding.
On top of that, they look way better than they are due to Tony's ability to play outside of the pocket.
All these Quaterback>Romo are stupid to say the least.
Romo is a top 5 quaterback, what else do you want?
