I thought before this fight Bud was possibly the most skilled and conditioned fighter of all time but I thought Canelo might be way too strong for him. The fact he's gone from lightweight to welterweight and then super middleweight against a fellow P4P superstar is pretty much unprecidated. The only similarities are Leonard-Hagler - which was far closer and arguably not a win. And Pacman against inferior competition to Canelo. I suppose there's Armstrong, but he was kind of a lightweight who could drain to feather and wasn't too much lighter at featherweight.
Crawford, as a welterweight, was probably very close to 168. When exactly did he fight at 160 pounds?
I suppose he could have fought at 160. But 168 was light heavyweight in Charles day. So you can match 168 Crawford against light heavyweight Charles
