If someone's open deep, he's throwing it. And that's not the bigger issue. The bigger issue is risking injuring it further.... which could force surgery, sidelining him for a much longer period of time? Do we risk that against the Rams?
You want to risk it against St Louis? I'd rather give Brad the start against St Louis. He can do enough in St Louis. We can then re-evaluate Romo next week. Give a chance for the swelling to go down. Also gives a chance for the OL to get their shit together.
It depends on the situation, in some cases I'm sure player X could play with this injury, though I understand perfectly if Romo wants rest.
Its not a matter if he could.... he stated he has asked the coaches to let him play. Its a matter of if he should. Can we beat the Rams without Romo? Is the Rams game worth risking Romo over?
Personally I wouldn't risk it to be honest. I've got Romo and Brad on my fantasy team (I have Kurt Warner but he's on a bye week now :/) so I'm good either way bro.
