X3 fights a year?

[Master]

Julio C Chavez did it and so did fighters from the past.

On the plus side, JCC was a pretty busy fighter. On the minus side, he routinely retreated to the friendly confines of Mexican towns to fatten his record against inferior opposition in non-title fights.

That was because he was trying to get to 100 wins and 0 losses. There was no way he was going to do that if he fought top challengers every fight. It also allowed the locals to see the great fighter which was another advantage to non-title fights.
