Nah the stoppage was perfectly justifed under the safty standards of US MMA, if anything I think Brock got more time to recover than most fighters do just as agenst Carwin considering he was offering little in the way of intelligent defence. Obviously a real fight wouldnt have such stoppages but then again a real fight wouldnt have any rules at all so when Brock was turtling on the ground Cain would have simpley soccer kicked him into a coma, the openings where clearly their for him to do so.
