I assume he meant if no season, and he has some of the 2020 frosh sitting there technically still frosh b/c they didn't play, then you are recruiting kids from the 2021 class it doubles up your frosh class.
That's a big question and concern right now in every sport - what are coaches doing and what are kids doing, not just at the high levels where guys could leave for the NBA, but think about a D3 program that has 4-5 incoming frosh, they don't play a season, then you recruit 3-4 kids from 2021 ... now you have 8-9 guys that are basically in their first year of the program.
Does the coach recruit less kids? Take away offers IF that happens? It's all totally up in the air right now given the state of the world.
