I think that Romo hasn't shown the ability to win the "big game" yet. But I wouldn't say "never". A few years ago, people here were saying the exact same thing about Eli Manning.

It's also possible to win in the NFL with a great team and a not so great QB. The Reskins won with Mark Rypien, and the Ravens won with even worse... Trent Dilfer.

And I'm not trying to compare the supporting cast on the Cowboys to either of those two great teams. I don't think that this Cowboys team compares. I'm just pointing out that championships have been won with average QBs or worse. And I consider Romo to be better than average.

I wouldn't write him off just yet.
