I see PBF's defense staying for a long time just like James Toney's, and Pernell Whitakers because of that shoulder, and how much ring experience they all had. Granted since becomming 38 and obesse Toney isn't as good defensively as he was or should be if he lost 20 pounds, but still alot of the punches that hit him aren't hitting cleanly even if they appear that way because he is rolling with them. I would say that PBF doesn't get hit cleanly to the head without him moving with the punch or partially rolling underneath it more than 4% of the time.
