My first throught after hearing that Schaub was probably out for the rest of the season is "We're Screwed".
I am not now, nor have I ever been a Leinart fan. I was not impressed by his showing in pre-season. I think Yates has more upside and will be better at some point.
But the more I read and think about this, I think Leinart can do the job. This is not last years Texans. We are not asking him to be Brady or Manning. We just need him to be himself. We have the team around him on both sides of the ball. If there is one thing that Kubiak does very, very well is training QB's and designing an offensive system that they work in very well. If Kubiak did not see something in Leinart, they probably would not have re-signed him this year. If Leinart did not see something in Kubiak and the Texans, he probably would not have come back.
This is Leinart's oportunity to show the world that he is not the bust most people think. As long as he keeps his head in the game and does not pull a "Rosencopter" he can do that. He has the physical tools, he just needs to keep his head on straight and we will be just fine.
