Marquez does not have a career defining win over another top p4p to justify him being an alltime p4pder or current p4pder. Yes he has potential but seriously at 35 how much time does he have.

Career defining WINS

Barreras - Got Nas and a host of others
Hopkins - Got Pavlik and again a host of others
Pacs - Got Barrera, Hoya, Marquez and host of others

Marquez - Got Diaz no way is a p4pder erm.... ohh and he drew to Pac WOW mayby casa but he was like 40
