I think we will see Young before Leinart. Kerry Collins has played like shit this season. Actually for the majority of his career he has been average at best. Then all of the sudden he has one good year and people think he's great. The only reason he was starting over Young is because he protected the ball better. Well now he is going back to throwing too many picks and he no longer is giving them the best chance to win.
As far as Leinart goes, I think he has a chance to be the starter next year, but until the Cardinals are out of the playoff hunt I don't see Warner getting benched. Warner was bad the first week, amazing the second week, and then average this week. However, I believe the cardinals have bigger issues then just the quarterback position. Also as good as the Niners have played I don't see any team running away with that division so Warner should be the starter for the majority if not this whole season.
