Canelo and his improved defense.

three reasons why that was an impossibility:

1. The canelo who fought saturday is leaps and bounds better than the margarito who fought mosley.
2. The mosley who fought margarito is leaps and bounds better than the mosley who fought canelo.
and
3. Mosley was fighting at 154, his worst weight class, where his age is magnified, and where he has no speed, reflexes, and power, and is therefore devoid of everything that once made him great.

there's no way mosley ever could have gone bombs away on canelo and knocked him out, considering the circumstances above. he would've simply exhausted himself, leaving him even more vulnerable than he turned out to be.

 

Shane did not throw because Canelo would have countered him. Shane was hoping for a late KO and thought his experience would carry him. However, as the fight progressed he knew he had almost no chance without exposing himself to a devastating KO.

If Shane would have gone all out in the first round he would have been knocked out for the first time. Do you honestly think a guy like Shane would be dumb enough to risk giving up the pride of never being knocked out?

 

Mosley is and was done, there's nothing he could do to win that fight, he even pull punches no power at all, the fight was a disgrace from the beginning and all fights that we know the outcome as soon as the contract is been signed for that matter...
