There is no good reason to bench Romo, at all this season. If he is truly done......let him have a whole season to prove it, so this team can move on. The last thing I want to see is him missing a few games due to being banged up or benched because of some lingering injury(cough). This will give false hopes to Jerry and Co for the next upcoming season and we might have to re-watch this again.
Even if they bench him, Weeden or whoever isn't going to make a difference except a worse draft pick. This should not have to be dragged out over a couple of years to figure out if he is done, lets find out now.
