I told my son before he even threw that first pick that he looked like something was bothering him. Granted, a few of those picks were due to just poor decision making, I think the one that Cox intercepted deep down the field (and maybe even the one Willis got in the endzone) was just lack of arm strength. None of the balls he threw looked very accurate. I'm not sure if it was his back bothering him, or just bad timing with the receivers, but if it is his back they need to get him out of there and get him some rest. They won't be able to win, I don't think, without Romo, but they can't win without him playing healthy either.
Like I said, they need to figure out what his deal was today and take care of it. That was an incredibly poor performance and, as much as I hate to say it because I'm a huge Romo fan, today's loss was mostly on his shoulders.
