True, but Grossman is always injured because he gets hit and doesn't have enough protection. He's a great QB and if given protection, he would be really good. Besides, I don't see Kitna coming into Chicago (a playoff team) and suddenly overtaking the starting QB role. Sure, he's better than Orton, but with a team like Detroit who's getting fed up with Harrington, who can't do anything with good receivers (Roy Williams, Mike Williams, Charles Rodgers), he'd easily fit in and get the starting role.
Other than that place, I don't see anywhere, other than Houston (if they take Bush, like they said they would), where Kitna would start.
