I woul expect Bivins to make a decent fight of it given his proven track record against heavyweight punchers. Bivins has multiple wins over: Curtis Sheppard Tammi Mariello Lee Q Murray He also beat: Turkey Tomphson Claence Henry So he is prety damn proven against punchers. Ultimately however Frazier is just the kryptonite for the kind of fighter that Bivins was and would likley win by TKO.
Bivins would win the early rounds, but he wouldn't be able to deal with the pressure Frazier enforced.Frazier TKO Bivins in 9 rounds, after two knockdowns.
