Kovlaev--Beats current Kovalvev. Kovalev doesn't like body punches and hard counters. Loses on points to prime Kovalev (gets outworked). Beterbiev--Beterbiev would violently get stopped. Beterbiev lacks defense. Bivol--Bivol is a real talent and should clearly decision Tarver in any scenario. Gvozdyk--Gvozdyk was given a rough time by a 40+ Adonis Stevenson. Stevenson was a southpaw of similar size to Tarver but was way behind in technique and chin and possessed third rate stamina at the time of the fight. Gvozdyk would probably be made gunshy and lose a wide decision. Gvozdyk is somewhat of a standup Euro fighter with limited adaptation to the pros, and Tarver wouldn't be bothered too much by that. Gvozdyk might elevate his game but he isn't there yet.
