He might have had a few undisciplined players, but he didn't have teams that comitted 10+ penalties every game.
There will always be players who are prone to commit penalties (for example flozell) but when the entire team is comitting bone headed mistakes, it falls on the feet of the head honcho.
The entire Dallas O Line has always been one of the most penalized offensive lines in the league, ever since it was assembled, back with Parcells. They flashed a stat up. Cowboys averaging 9.8 penalties a game this year. Up from 6.9 (or something close to that) in Parcells last year here (2006). I wish they would have shown 2005 and 2004, but they didn't.
I do think Romo is part of the problem, but he is very serviceable and puts up stellar numbers usually. I think Steve Young hit the nail on the head during pre-game. You have to put the team on your back and carry them, and he hasn't done that yet this season. Instead of offering excuses on this pick, or that pick, don't make excuses and say "Guys, it's my fault." Now, all of that said, I do think Romo is a leader. I think as with anything, he could use improvement. As proof, refer to last night's game. That entire team laid down when Romo went down. Offense, defense, and special teams all gave the fuck up. If that isn't proof that Romo does lead (though he could always do a better job), I don't know what is.
And as I've been screaming all season, turnover battle and penalties kill them every time. Offensive play calling is fucking horrific. It's like something out of a bad movie. 2 yard bubble screen on 3rd and 7? Has that play gained positive yardage yet this year? Halfback draw from the gun on 3rd and long, when you're down by 18? Brilliant play calling, Jason Garrett. Just fucking brilliant.
