Our failure, in the case of Romo.
Look, I love Romo and appreciate what he's done. But many Cowboys fans bend over backwards to make excuses for him. If he doesn't get it done, it's always "He can't do it alone. He needs a running game or a better defense or better play calling, etc."
But now that he's on the bench recovering from injury and the Cowboys are doing well, it's "Well, with that offensive line who couldn't play well" or "With Ezekiel Elliott, Romo would be even better" or "Now that the defense is playing better, we'd be destroying teams with Romo", etc.
I don't want to lose this momentum, which is why I favor keeping Dak in even if Romo is healthy. But I would like to see what the excuses would be if we inserted Romo and we fell short again. It would probably be some other excuse. Yawn.
