I read that Missouri is down to 64 players for various reasons. This is a copy and paste from a Gainesville Sun article:
Thinned-out Tigers
The Tigers are down to 64 scholarship players for Saturday's game, 21 below the NCAA limit. The low number is the result of injuries, opt-outs and transfers.
Taking a page out of Mullen’s playbook, Missouri coach Eli Drinkwitz is not revealing any injury information this week for Saturday’s game.
“We’ll just play that game, too,” he said Tuesday.
It looks like a lot of teams are playing shorthanded this year due to Covid-19, players opting out and entering the transfer portal, plus injuries. It's good that games are being played, but this will probably be a throwaway year insofar as evaluating coaches and a lot of players. From what I've seen the Final 4 will be the same cast of characters - Clemson, Bama, Ohio State and a designated loser.
