for a number of reasons. Tony Romo will need an eventual replacement. There's no guarantees he'll recover fully from his back injury. A youth injection might be needed. But there's a much more important reason than that.
Jerry's only interested in Benjamins.
Let's be honest. Jerry's got huge debts. He also can't build a team. He doesn't understand football well enough to play a 'real' NFL general manager. The team will continually be stuck at 8-8 but he needs to fill a gigantic stadium. Enter Johnny Football. Enter controversy. Enter ratings.
#2 overall pick QB's don't cost as much to sign to rookie contracts as they used to and the Rams want to trade. If he's not gone by #2 overall Jacksonville at #3 will probably take him. Jerry won't let that happen. He's not going to any other team. The only thing that make sense is if Dallas trades up for Johnny Football.
