If he wins this fight, he wont have another mandatory for a year. He will brake Marciano's record. Then everyone will walk around saying, yeah but Marciano was a World Champ not an alphabet champ.

This will inturn take credibility away from all alphabet champ records. Tyson will go from being youngest heavyweigth champ to just being youngest heavweight alphabet champ

Holyfield will only be a 2 time champion, and not a 4 time champ when you count all his alphabet titles.

It further will diminish the value of the alphabet titles.
