He rematched Brewster and beat him. He desperately tried to get Fury rematch. He did have rematches with Thompson, Byrd, and Peter who gave him tough first match. I saw no point in Purrity rematch. Wlad dominated that and gassed out fighting in front of him home crowd for first time. The stand out miss - is Sanders. But honestly a hard hitting southpaw - I would of advised against an immediate rematch myself with that one. And then Sanders lost to his brother and kind of faded from division. But it is a missed opportunity for Wlad.
To be fair to Wladmir, he did try to avenge the Fury loss but Fury did the typical f*** boy maneuver and retired while still on top (after a very dubious and not very convincing fight), while somehow managing to sweep the PED accusations under the rug by distracting people with his mental health sob story. In reality, Fury simply had no discipline and got fat and lazy just like Buster Douglas, Bowe, Ruiz, etc. He didn't want to risk potentially losing to a motivated Wladmir out for blood. Fury is the one who's insecure about his own win and constantly harasses Wladmir online while Wladmir just ignores him.
