Yes, NCAA meeting tomorrow looks like will indicate when season starts. Looking like weekend of Thanksgiving so they can play all through holidays with no students on campus to start. Looking like just playing a few 4 or 5 non conf games, and then all power 5 playing 16 to 20 conf games.
Big 10 & PAC 12 basketball can't start during the fall semester according to those conferences cancelling all sports for the fall semester.
Maybe they will change course on that, but I believe the NCAA will state an "earliest allowable" start date and then each conference will determine how they will work with that time frame.
