If that punch had not landed?
Hatton went down twice in first rd, JMM went down 3 times and came back.
Please consider the following:

Hatton was landing on Paq, not an amazing amount, but he landed more in 2 rds than Oscar De La Hoya did in the entire fight. Paq has said that Hattons puches were hurtful.

Although Hatton went down in rd 1 twice, he had not gone down in rd 2, in my view he clearly was having more success in rd 2 than rd 1, although Paq clearly took the round.

Consider the fight was of an incredible pace which could not be sustained, I believe if Hatton had survived another 2 rounds, Paq would have slowed down giving Hatton a chance in the later rounds.

I am not saying Hatton would have won, all I am asking is would he have had a chance later on if Paq slowed down?

The fight was an incredible 7 minutes worth of action and to me showed me why no other sport could match it when at its best.
