Draft. SMU had Omari Abor, Preston Stone, Jahari Rogers opted out when they played Penn State in the First Round in 2024. Likewise, Penn State had Beau Pribula, T.A. Cunningham, and Feyisayo Oluleye opt out that same year. I'm sure there are other examples out there. As far as whether the players were starters or backups, I am not sure it really matters. Particularly if that player still saw significant PT during the season. Even if a player saw little to no PT during the season, it could still be significant if basketball starts to see a similar type of behavior. Particularly if a team is forced to dress 7-8 players for a game and that team has multiple players foul out during the game to drop the number of eligible players below 5.
