He's already suffered a severe ACL tear in his first year. His success is mostly predicated on being able to execute the option offense with him being a big part of that running option threat. These type of QB's never last. His only hope to last more than 2 years, IMO, is to become a drop back passer. Then he's one dimensional like the rest and his success will suffer. His window is about 2 years. It's a crap shoot that he stays healthy enough in the next 2 years to take the Deadskins to the playoffs. After 2 years, it's over. Probably less.
