I don't mind when Archie Goodwin drives one against three and they call the charge. I expect that. It's when Alex Poythress gets a foul at the top of the key trying to lean around the defender to make a pass and the guy flops. Honestly, I think that's the call that got under Cal's skin and why he said that. It was 30 seconds before halftime.
That word lean means that was the player who created contact. Which will go against you everytime. You can't lean around a defender infront of you. You're leaning to create space which is a foul.
