Gene Fullmer perhaps deserves a mention. Very rough inside the ring, but very popular with everyone who met him as a "civilian." And Fullmer reminds me of Dick Tiger, another always nice gentleman.
I Met ...D.Lopez, W.Mccullugh,Alex Garcia,CArlos Palomino,Tony Lopez,Mike Weaver,A Muniz and Julio Gonzalez, and all were class acts.
I am sure the teacher he layed out may disagree. Bruno seems to have a split personality, I have heard stories about him losing his cool with fans and allegedly his (ex?) wife, Laura. The nicest boxers I met were James Oyebola, Hughroy Currie, Scott Welsh and (somewhat suprisingly) Chris Eubank
Not the nicest in history by any stretch, But Liston did always check on the condition of fighters he knocked out after every match. Not bad for what was considered the most brutish man to have laced them up at that point.
John conteh is not really a nice guy he knows some very dodgy people and if you ****ed him off you would find out he is not as nice as you think. I would say riicky hatton is easily one of the nicest fighter's of all time, he still lives near his parents, he owns the local pub and is well liked by everyone in the uk and especially the people round the area he lives. He said he would be gutted if people thought that he thought he was better than them and tries to live as normal a life as posible.
