It was raw old school stone age man who gave beating to modern tattooed instagram soyboy. This fight proved that Jack Dempsey or Jack Johnson would beat most of the todays fighters.
In my time teachers wouldn't touch students. Not because they were "enlightened" or something like that, but because they would be the ones receiving the beating.
Stop would you. Dempsey isn't half as skilled artur and Johnson as great as he is would get disqualified by todays clinch elergic rules.
It's not that, but merely that in the time I went to school there was a huge growth spurt going on in my country, with many young guys over 6' 3" from a very young age on, including the athletic ability coming with it. Also, combat sports had a huge surge at the time, with lots of guys doing martial arts or kickboxing. So, many students were bigger and stronger as the adult teachers of that time. I heard my economy teacher once stated "Nope, if I try that I will be the one that gets knocked out. Let them sort it out among themselves and then we can sanction them afterwards." After being asked if he shouldn't intervene. The groth spurt has levelled out a lot since then, in most part due to mass intergration, but at the time it was quite noticable.
