Who wasted more potential Adrien Broner or Deontay Wilder ?

Wasted? Wilder overachieved if anything. Could he have worked on his craft and developed more, sure. But he started boxing super late and pretty much maxed out , especially looking at his legs and limitations with coordination.

Wilder was guided to riches and recognition that was well beyond anything his skills some could earn him. Broner had more potential. Mind you it's hard to think anyone has failed to reach their potential when they've been a world champion. It's not a bad achievement! The one I think really didn't reach his potential is Fury. Imagine a dedicated Fury from 2015 taking good fights. He might have been something really special and could have been out of the sport before Usyk arrived in the division.

I think Broner could have been a lot better, Wilder I feel did fine for his ability level

soon it will probably be tank, broner, or wilder. well maybe not so soon since i think tank is learning from their mistakes and making sure his opponents are even worse and more debilitated

Broner had greater potential, Wilder never had potential to be better than what he was/is.

Broner and it is not even close

Broner was a 2 weight champ (light & welter) before 25 I believe. He should have been a long reigning champ at 135 and 140 when those divisions didn't have anyone notable and instead squandered everything because of his ego and not letting his hands go.

Broner hands down, he was much more talented. Wilder overachieved, while Broner underachieved.
