Seems slightly odd that Devin says he was frustrated at himself, not the call... and then stares at an official. That makes no sense.
It makes no sense because it's a lie. He was angry at the official. He stared and barked at him. The official warned him no more. Devin continued. Devin received a technical.
Life isn't that complicated.
Devin continued what? Staring? Sorry, nowhere in the rule book does it say you can give a kid a T for staring.
