100% a flagrant foul. The NCAA rules committee along with Art Hyland and JD Collins want to eliminate the "hook and hold" play from the NCAA game. This includes both on the perimeter where a cutter or offensive player tries to hold an opponents arm trying to fool the referee and get a defensive foul call, and in the post area where players will grab another players arm which is a dangerous play.

This was an excellent review and call.

There was a hook and hold play in the UK-Duke game which they did look at but, incorrectly, did not upgrade on video review. JD sent out a hellfire and brimstone video referencing the UK play an others saying "we want this eliminated from the game" and "if you call it, they will stop doing it".
