Obviously this won’t work for all sports, but things like football, track, soccer, it would allow for de-gendered team, even allowing athletes with the skills but not the genetically-endowed physical attributes to have a place to play.
Note: I know very little about sports and being on a sports team, so please point out anything that doesn’t make sense.
Dunno, you might wanna just watch UFC 1. If you’re really high level you might wanna watch nog vs sapp, though. Best one I’ve seen that’s actually at that level, even though the weight disparity might not be so extreme as you desire outside of like, basically carnie shitfights like eddie hall fighting twins.
