Also Wladimir Klitschko's chin isn't THAT bad....Clifford Ettienne's chin was faaaaar more fucked up than Wlad's and RJJ's chin wasn't an issue until he got blindsided by Tarver. I think you can see Wlad took some pretty solid shots off of Sam Peter (the legal ones at least), Lamon Brewster (in the first fight), and Corie Sanders...he took one shot (a left cross) right on the button and got back up....his legs and psyche didn't keep him up long but he got right back up.
