HWs today are in better shape? Have you seen the fight of the century or the thrilla in Manila in the blistering heat? Incredible endurance that no heavyweight today could even remotely come close to. The thrilla in Manila was one of the greatest feats I've ever seen. Then you have AJ gassing today in half the temperature after doing a 5 punch combo. Are today's heavyweight's bigger? Yes, but please, does that matter so much when they are less skilled & have less stamina. Larry Holmes would play tig with AJ's face until the Watford man gases & gets stopped. Tyson would destroy Joshua & Wilder too. May I add, I'm not as harsh on AJ as most people here but to me this is obvious.
