That's my understanding as well. I think the staff is concerned that one (or more) of the players MAY come back to campus after going home for Christmas and being exposed to various friends and family members, and test positive, thus setting the program back another 10 days (as they quarantine) again. UConn is still playing catch up from the first quarantine. Villanova has already played 7 games.
Games are still be canceled and postponed, ergo:
"from ESPN this morning - UC San Diego's women's basketball team will have to wait before it can play its first game as a Division I program. The Tritons' game Monday against California Baptist was canceled at halftime because of coronavirus testing concerns. Prior to the cancellation, the Tritons led 28-25. Because the game didn't reach the 30-minute mark, it didn't qualify as official". Per ESPN, 12 scheduled games today have been canceled or postponed today.
