I think Bolles so-called "power" comes from his mental demeanor and aggressive attitude.  That' all great, but his so called "power" wasn't evaluated when he opted-out of the bench press drill at the scouting combine.  Chances are, he has not yet developed a lot of upper body strength and that is risky in game-play with his street-fighter mentality.  He could tear a tricep or pectoral muscle easily.  But if he can stay healthy through his rookie year, he should be fine in the long haul.
