I seem to recall Jay Bilas advocating for a return to the round robin, even at 22 regular season conference games.
That would make the ACC season more exciting and more fair. The stature of the regular season winner would rise even more over the ACC tournament winner.
On the other hand, that would leave only 8 or 9 out-of-conference games. Those out-of-conference games are important preparation for the NCAA tournament because of the opportunity to play types of teams we may face in the tournament but don't see in ACC play.
Also, we would have to start conference play probably in late November, before the team may have been sufficiently hardened to withstand the intensity of conference games.
