I guess my response to this would be Ware and Witten dont do things to single handedly blow big games, the way Romo has repeatedly now.
Further, even though I feel Romo has peaked, he still has significant trade value and the team can clearly use what we'd get in return to reload/retool other positions. Personally I dont think the drop off from Romo to Orton at this point is that severe, especially if they fortify the OL a little more. There'd be a drop off, no question. But for all the good Romo does, he has the one flaw I dont think will ever be corrected or be coached out of. Thats why I think it might be time to move on from him.
