I don't think that Mike Holmgren sees Russell Wilson as the "Prototypical" Quarterback.
My gut tells me that he recognizes that RW has the wheels, and Football savvy all but lacks one of the bells or whistles in Mike Holmgrens estimation.
I think Mike sees RWs height as a possible hindrance to reaching the pinnacle, but probably has talked with Gruden, for which he'd maybe be swayed in his perspective to take the wait and see, but old concepts sometimes just never seem to wane.
Mike Holmgren is right about giving Wilson room to grow into the leadership role, as the Franchise QB for Seattle.
I agree that there will be bumps in the road for Wilson for the next couple of Years, but Wilson seldom ever makes the same mistakes twice.
