If the junior divisions hadn't been created how would that effect boxing today and those fighters that are would champs in Jr weight classes?
Well, they'd possibly be champs at the non-jr weight divisions. That's what they'd have acclimated to. There would be less champs, but I don't think much else different.
Guys that stayed at the Jr or super limits would of been forced to try their hand in a more traditional weight class. I'm specifically thinking of Terry Norris either cutting to welter or going to 160 and Kostya Tszyu probably going to 147 as well. Ricardo Lopez, rosendo Alvarez, Gonzalez, Mark Johnson and Carbajal all would of fought at 112 for their titles instead of split between 3 divisions in the 90s. Guys at cruiser would probably compete at heavy with mixed to poor results. With 4ish titles per weight class we are cutting out over half of them if this happened so guys wanting to win a title are going to have to face better competition for the most part. Winning titles in multiple weight classes would be more impressive
