Chavez Jr is a fatty says Arum

[fan johnny]

Chavez's stop at 168 would be brief. He could easily move up even higher. Enough of the gaining 20-30 pounds by fight time. It's been Junior's recipe for success against lesser opposition, until he got schooled by Martinez. Let him go up and fight fighters his own size.

I could swap the names out on this and apply it to many fighters.
