On March 10, in the midst of the ACC tournament, against Duke's archrival, Grayson Allen missed a jumper. When the rebound was corralled for a potential fast break in the other direction, Allen responded with a hip check of North Carolina's Garrison Brooks. It was so incidental to the action that the referees initially missed the call and the Tar Heels scored on the other end anyway.
All of this would've been less than a footnote in the game had the name Grayson Allen, a player vilified for tripping opponents, not been attached. Instead, Allen was assessed a Flagrant 1, Twitter went insane, and every basketball fan who was not also a Duke fan immediately became enraged at Allen all over again.
