Why did Marquez lose when stepping up?

[TheBoxingXpert]

He lost to Norwood. He lost to Chris John. He got absolutely schooled by Mayweather. He lost to Bradley. I mean... He is good, but how come that the only good fighter he was able to beat is Manny Pacquiao? Is Marquez really just an above average boxer who just happens to have the perfect anti-Pacquiao fighting style?

The names you mentioned are pure boxers, JMM needs a bull type of fighter to look good against, he really can not lead the fight at all. So when there is not much to counter he tends to look bad

[danceswithfire]

jmm is an excellent fighter but not a special fighter. his resume is too weak to be considered an atg either

[Kel1981]

He is a counter puncher

Exactly and people forget he's up there in age as well.

[SeekDaGreat]

He did his thing, won some big fights, and lost some big fights. I don't see him as losing every time he stepped up. Juan Diaz was supposed to knock him into the next Millennium.

Barrera and Pacquiao are okay wins, but those other 3 shouldn't be mentioned.

[Real King Kong]

He was ripped off against john. Going to Indonesia to fight john while holding out for more $ for a pac rematch was the worst move of his career. Turned down around a mil for 300k and an L.

This. Plus, he was 40 when he faced Bradley, well passed his prime.
