Don't blame Tony, he's not the reason why we lost.
He's not THE reason we lost.
There are lots of reasons.
He was 30-42, with a TD and a fumble. He probably had half of those incompletions the last drive. He made a really bad audible on 3rd and goal from the 9.
But we also had a dropped pick-six, a defense that couldn't get off the field with 4:30 left, a fumble to stall a drive, a false start penalty on 3rd and goal putting us in the bad spot where Romo went to the bubble screen, a dropped TD by Dez, etc, etc.
