The ACC is historically bad this season.
The league that had three No. 1 seeds last March only has four teams with the credentials to make the projected NCAA tournament field. Usual power North Carolina is one loss away from last place in the 16-team league, defending national champion Virginia is on the bubble and the conference ranks sixth among seven power conferences in the NCAA’s NET rankings.
So what does this mean for the league’s top two teams — Louisville and Duke? It means both teams, currently projected as No. 2 seeds, have little room for error if they want to move up to the top line. For instance, if the Blue Devils would have lost a road game to archrival North Carolina on the weekend, it would have qualified as a Quadrant 2 loss. Should they lose to UNC at home March 7, that would be an even worse Quadrant 3 loss.
It also leaves less…
