which is the more impressive feat:by Pacquiao or Mayweather jr?

[check hook]

never knew Pac defeated Marquez. may be that was Arum?

Realistically you could give the first 2 fights to Pac by a c*nt hair, but the reality is that JMM beat him convincingly in fight 3 and left no doubt in fight 4. There is also the pesky matter of Floyd pitching a shutout against JMM, so bringing that win into the discussion doesn't fly imo.

Since Pacfans are out in full force making excuses for Mayweather wins against Corrales (weight drained) and Hatton (couldn't fight at 147 only at 140) lets look at these great Pac wins.

Barrera had a surgery to repair blood vessels in his brain, then lost training equipment needed in a fire during training camp.

Morales lost to Barrera, beat Pac, got dominated by Raheem, then had to drop weight looking like one of those kids from the "feed the hungry" commercials...only thing he was missing was the flies crawling on his face. Also he was on the downside of his career.

Marquez....questionable wins when most people are asked and he put Manny to sleep at 39 years of age

Yeah Hoya looked so fat and out of shape against Floyd. Moron.

Hoya was at his best against Floyd. 154lbs with a title at the time.

if you lose to zahir raheem-and by a wide margin-then you are no longer a world class fighter.

Yes, because everything is as black and white as that. Because there are absolutely no other examples of top level fighters being upset - often in a comprehensive and decisive manner - by significantly lesser known underdogs.
