They share a lot in common when it comes to style and technique but Arguello's edge in power and reach win it for him.
Marquez gets hit too much to beat Arguello ... Good fights, obviously but I'd take Arguello in each weight class
JMM would have his best shot at 126. I think he goes the distance at most weights, certainly wouldn't be a massacre. Gotta remember he might well have fought in higher divisions with same day weigh-ins. Good fight either way.
At 140, Marquez would have Panama Lewis in his corner between rounds "gimme that bottle... No no the other bottle... The one with the piss ... The one with the piss"
