That's looking at it too narrowly though. Wilson is asked to basically not turn the ball over. He does that really well, but at the cost of actually being productive (hasn't had a season over 3,500 yards). This, in turn, inflates his QB rating.
It works for Seattleright nowbecause they've got an amazing team built around him. If you put him on almost any other team though, he'd be required to actually carry the team like most other QB's. Can he? I don't know.
Once again, the Seahawks didn't have a choice. That's just what you pay a franchise QB. But when the pieces around him finally move on, it'll be interesting to see if he's actually worth a shit as an NFL QB.
