Worth considering...both fighter are all ready all time greats. But...

1. If PBF wins...his rep improves but not dramatically...and not nearly as much as if he had beat PacMan a few years ago. The latter, imo, would've skyrocketed him onto to shortest of shortlists for all time greatest boxer (arguably #3, after SRR and Ali). But now, he has little to gain.

2. If PacMan wins...his rep skyrockets b/c he becomes the first man to vanquish the undefeated All Time Great. He then enters the aforementioned shortest of shortlists.

The risk/reward is there for Pac. But for PBF, he has more to lose than to gain. The fight may not happen for that reason.
