Well he did deserved to win in my opinion.
Perhaps if you look at it like:
Guy runs away from giant to avoid a fight and tries to get a few shots in.
I prefer to look at it like this:
Guy shoots his mouth off and claims he will be the first to knock giant out.
Guy spends 12 rounds running away when he realises he will get hurt if he gets too close to giant.
Yeah he threw some good punches at the end but he should have started earlier to get a little more respect cos he certainly didn't live up to his big mouth expectations. Boxing needs an overhaul - that fight smacked of a Don King deal.
