Manuel is out for the preseason. Kolb has a concussion likely. Highly unlikely they need to trade for someone, let alone Sanchez.
Kolb should be cut the way he has played IMO. That said they still have Tuel who hasnt looked bad. Manuel is the man when he gets healthy but I think Buff would be well served with Tuel. Also this is Buff you really think they will pay that much money for a guy that will be their BU? Unless Wilson died last night. Which Im not discounting. Not going to happen.
