Just a few hours after CBS’s Selection Show ended, the college basketball transfer portal opened for business, with some schools processing transfer requests barely after midnight.

On the men’s side, players from Maryland, Miami, and Stanford are among nearly 300 transfers who have, as of Monday morning, declared for the portal. About half of them let their school know their decision since the portal opened, per tracking by Verbal Commits. On the women’s side, more than 215 players have declared for the portal, according to The Next.

It’s the second year the transfer portal has had an official open date on the Monday immediately following Selection Sunday. For football, the portal opens the Monday after FBS conference championships—essentially the same schedule as men’s basketball, although football’s Saturday games give an extra day in between. In all other fall, winter, and spring sports, the transfer portal doesn’t open until a full week after championship selections are made, giving players and coaches a bit more breathing room.
