I'm actually intrigued to see how Weeden plays in the preseason. He's a career backup now, but might end up being a pretty good one.
On Orton, I sort of agree with the consensus, but I will say, the guy has reportedly been working his way out of the league from the point where he took the backup gig in Dallas when there were jobs like the one in WAS wide open. I'm not sure how much has changed during his time here. Very possibly, he's a guy who's capable of playing decent football even with his heart not completely in it. He definitely lets us play our full passing game when he comes in in a backup role...that's pretty important. Nobody else we play in his stead would let us do that. If we rolled out Weeden in week 17 last year, we'd be running the ball and trusting to our defense rather than throwing it as much as we did, for example.
In any event, I think the guy ends up coming back for one more season. At least, he's in camp and we get to see how he plays compared to Weeden and make our decision then.
