I am not a fan of resting Dak or any rookie QB. I think they need to play,espeically given that Dak has been struggling, he needs to work through it. But to answer the question, yes, Tony would want to play. As much as he says he is good to go, in the best shape, etc, until he get hits, he and the world will not know if he can be hit. He has to have some doubts as much as any of us do. He wants to play, he wants to audition for his future team and at the same time, help this team win some games. I do not think the coaches will allow him to play, what if he comes in an lights it up and shows he is the Romo of past. And then we lose in the NFC Championship game and Romo is on the bench.. now Jerry might overrule them so he can start the bidding for Romo. IT will be interesting.
And if Romo should get hurt again, its retirement time, no if or buts about it.
