No, if anything I think it continues to improve as he works out for teams. It's gonna be a while until his rights are traded, if in fact they are.
Really? The Browns? Garcia should do well for a couple of seasons and Kelly Holcomb seemed like a good QB, himself. But I guess it makes sense, since Garcia is 34, Holcomb is 31 and Couch is most likely gone due to his salary. I did see where the Browns had interest before Garcia signed. Overall, I do not see Garcia as the best QB for Henson to study under, as they do not seem to be the same type of QBs.
Expect things to be quiet until the initial free agency push is done. teams are focused on that as is his agent. this is a game of brinksmanship and the teams that really want him are just being coy. Nobody wants to come out as being willing to even contemplate what Henson's agent is asking for. As soon as one team blinks, another will join in and Henson/Houston will pick the preferred destination.
