Boxer/Out-Fighter?? (as defined by wiki) PBF certainly qualifies, as would Ali. Malignaggi doesn't. Part of the definition is "wearing down of your opponent with out side punches" i.e., the jab. What your boy Malignaggi does is throw a lot of punches that are so weak, made weaker by he is leaning backwards. He doesn't wear anyone of any quality out. He couldn't box his way out of a paper bag. Malignaggi needs his own definition. I'l make that a topic...
Hagler and Trinidad were not really brawlers. Hagler was first and foremost a boxer-puncher and Trinidad was more like a patient stalker. I like different varieties. I think it's the punching form and technique play a big part in whether or not I like watching certain fighters.
