First, we have some retired numbers. So there are some numbers we do not assign.
Second, there are certain numbers that tend to be reserved for certain positions. So we tend to see numbers in the 50s, 60s, 70s, and 90s which are not fully assigned out to all of the players.
Finally, though the rules have not yet been put into place (August 2025), we are about to be allowed to have 105 SCHOLARSHIP players. Thus...well, you can do the math. I know it doesn't answer your 2024 question, but it's about to become a thing.
