I never understood why 21 was considered a free year of eligibility while seniors from 2020 (and everyone else who competed that season) got hosed. The only logic I've heard is that in order to incentivize wrestlers to compete in 21, when it was unsure if the championships would be held due to the ongoing pandemic, the NCAA offered it essentially as a preeminent mulligan.
But if they were willing to give the free year for 21, why not 20 as well? Just seems arbitrary and capricious. Never sat well and still doesn't.
