Are you serious? Muammad Ali had the most infamous temper ever, both in the ring and out; he has been a shame for the boxe
The guy who knocked his opponent spark out after a fight and also murdered Kellermens brother.. his name escapes at this moment!
Like previously mentioned, Ali. He was outright nasty to many of his opponents, especially Frazier when he and Frazier fought their first fight. Roberto Duran was known to be pretty vile to his opponents and I saw him several times in the ring grab his nuts and sneer at his opponent when he KO'd them. Tyson wanted to eat his opponents children according to his statements in a press conference. I saw many press conferences where he was over the top in his comments and came off as a complete sociopath.
Mike ****ing Tyson. Canelo also has a very violent temper. He tries to come across as a sweet redhead who's always polite, but in secret he has already attacked several men who have talked to his girlfriend.
Jake LaMotta had a legit bad temper...but really so did guys like Joe Louis....really...it almost more relevant to ask "Name a boxer who doesn't have a temper" because that would be a much more concise list.
That's a better question i think , ''boxers with no temper'' ?, i'd probably say Muhammad Ali Max Baer Ray Leonard Rocky Marciano Tony Zale
