Yeah, he just had back surgery about a month ago. He'd be the best of the free agents, if not for that.
In fact, Indianapolis contacted him when Peyton couldn't start the season and was told about the back surgery at that time. Even so, Leinart is the better choice. Garrard wasn't released from Jacksonville for no reason and would be a poor fit for the Texans with his lack of accuracy.
Maybe Manning will be ready for playoffs and we can cut a deal with the city of Indy, offering them the Dynamo for him.. That's fair right? They are drafting Luck anyways.
