Most of the people who criticize fighters of Louis's day don't really attack Schmeling's skills as prehistoric. Unlike, say, the Baers, Galento, Sharkey, Carnera, Simon, et al. I've seen Schmeling characterized as unexceptional -- just a so-so counterpuncher of moderate size -- but what was primitive about the man?
Please feel free to offer some form of breakdown, so long as it isn't "big man from 90s knocks everyone out"
He struggled so much that he knocked Conn out twice. You can nitpick one fight in such a long and tough career. Meanwhile, Morrison literally lost more times than not when he faced world level contender.
Honestly, I think "90s Lifter Steroid Man Knocks Everyone Out" is not a terrible argument, since it trades on a pretty significant ambiguity. We know Louis didn't have access to any modern PEDs or training techniques. We also know that Morrison admitted to using them. Most importantly, we lack information about just how much of an advantage 90s gym sorcery gives you, because we can't be sure quite who was using what. So somebody could make a guess that the effect is significant enough to propel even a "mediocre" elite athlete like Morrison to victory against the boxing equivalent of Jesse Owens.
Buddy Baer is trash and methodical, i obviously give him a chance because Morrison had a glass jaw but he also most definitely had better head movement and quicker hands. Morrison would likely KO him
