I'm ok completely disagreeing with you on this. It's more of the same as far as I'm concerned: if the play didn't work, then it was a bad call. If it works, it's a brilliant one. That's just not how I evaluate play calling. I'm ok with running the ball on 3rd and 2 with our OL against their DL if we think we've got a play we can win with. I'd be ok throwing it to Witten, too, but it's not like I was seeing a lot of open receivers downfield yesterday. Sure, with Romo I'm ok having him give Dez a jump ball or three. Or trusting that he can read his BFF's mind and get the ball where it needs to be. I haven't seen anything from Cassel that makes me want to take that chance when the alternative is putting points on the board that will give our defense the lead again.
Garrett *did* play it really conservative yesterday, at home, vrs. the two-time NFC champs, with his backup QB, and a defense that was corralling their offense the entire day. Forcing the ball into that secondary on the compressed side of the field on the arm of Matt Cassel would not be the decision of a great football coach. It would have gotten us picked, or nothing. Then you'd all be complaining about the mediocrity of that since you essentially get to have it both ways after a loss.
That doesn't change the fact that there's a dumb way and a smart way to handle that situation yesterday with that down/distance/game situation. You take the points, take the lead, and rely on your defense.
