Benn should have been disqualified (Or at least penalized with extra time for Barkley to recover) for that shot while Barkley was down. It was way more flagrant (and damaging) than the one Jones got disqualifed for against Montell Griffin.
Speaking of Hill, I wouldn't have expected to stop the typically durable James Kinchen within one, either. Kinchen had just went 12 with Hearns and Roldan took 9 to stop him. It seems like James lost most of his durability when he moved up to LHW. He also ended up getting stopped by Charles Williams in two a bit after this bout.
