Sage Rosenfels Has Signed With The Miami Dolphins. Last time we saw the former ISU quarterback in an NFL uniform he was pinwheeling through the air from one side of Reliant Stadium to the other. After losing Chad Henne to a season ending shoulder injury, Miami was down a QB and turned to an aging Sage Rosenfels for some added depth. He will likely compete with current Dolphin back up Matt Moore for the starting position. Hopefully this time out Sage will choose to slide!
