Wrestling may be the most inclusive sport there is, but don't get that twisted. Just because "any body can wrestle" and all are welcome does not mean parity exists.
What it means is you're welcome to come get your ass kicked.
The weight classes do their best to smooth out the playing field, but at every level of competition, in any of wrestling's multiple competitive structures, there are always, always at least some extremely unbalanced battles.
In fact, using lenses to view the perspectives of either the Favored or the Underdog, we can see that wrestling’s scoring structures are designed to incentivize each of them!
