If Briggs beats Browne, that will be a huge boost to the legacies of Vitali and Lennox

Reckon Browne will win, he went long hard rounds with chaggers. Whilst Briggs probably has 4rounds in him tops. But who knows

 

It wouldn't affect the legacies of Vitali or Lewis at all. Briggs is garbage and, if he somehow wins this fight, the only person who's reputation (such as it is) will be effected is Browne.

 

It wouldn't really effect Lewis, his legacy is too established. But for someone with 9 title defenses in his main reign, Vitali has some semi legit questions about the validity of his defenses. I'd rate them in the 30-40th percentile for champs. Briggs was one of his weaker defenses right now, but if Briggs were to become a 3 time belt winner 6 years after they fought, it makes one of his weaker defenses one of his stronger ones and his overall reign less assailable. To some extent, at least. At the end of the day, the guy still had 9 successful title defenses in his late 30s and early 40s and it's hard for non psycho haters to find too much fault.
