So you didn't realize this last year when Weeden started the Cardinals game?
There is not even enough quality starters in this league at QB much less expecting a backup to come in and win games. Did you see what the Packers looked like last year when Rodgers went down? Pretty awful.
I will agree that Vaughan and Weeden are terrible and having someone else would be better. Orton and Kitna were very serviceable and both were starters as well in their careers.
Weeden started the Cardinals game down two starting offensive lineman, with a hobbled Dez Bryant, and absolutely no help from Murray who decided not to show up that day. All this against what ended up being the 5th ranked defense in the league.
Not to mention a majority of fans were lauding Weeden the week before and claiming that we would have won the Washington game if he had stayed in the game.
I doubt Romo would have performed well against the Cardinals either. Our team was hobbled, it was one of those weird days, and we were due for a loss like that.
It's time to stop judging Weeden based on one loss. We'll be lucky to go .500 with any good backup. That's just the way the league is unless you happen to catch lightning in a bottle. The purpose of a backup is to get you through a couple of games until your starter can get healthy. Weeden is capable of that. If you're expecting your backup to come in and light it up like your starter, then they wouldn't be a backup.
