While the focus will undoubtedly skew toward Duke — with or without Cooper Flagg — UNC, Clemson and Louisville are coming off thrilling finishes in their own quarterfinals.

We know what Flagg can do but with Brown, UNC found out first hand on Saturday. When Brown entered the game in the second half with UNC up seven, Duke went on a big run. He essentially took RJ Davis out of the game with his length and he's an issue on switches for guards.

If the Duke Blue Devils want to be the No. 1 overall seed for next week’s NCAA Tournament, they need to convincingly win the ACC Tournament. That quest started Thursday.
