I think he'll be back if Romo is successful. Look at what he's done since he's gotten here, despite the records. The skill positions are better than they've been in a long time and the defense is turning into one of the best in the league. That doesn't mean they're the best every weekend, but on average, they are one of the best.
The focus of next year's free agency market and draft has to focus on the O-line. Instead of spending $25 mil on one player, spend $20 mil on two or three good offensive linemen.
