Richmond vs. Charlotte End of Game

[Judtech]

If it weren't for the 2 handed push at the end you could have gotten away with a personal foul. But with the push coming late in the action you didn't have a choice.
Calling the shooting foul is still a head scratcher. It looked to me the first time, and every time since, that the Charlotte player left his feet to pass the ball back to #44. Once he hears the whistle it appears is when he decides to 'shoot'. To me it goes back to what is more likely in a situation. Is it more likely, with his team up and the other team looking to foul, that the kid was passing to a team mate or shooting from 45'? I would like to see when the official signaled a 3 point attempt because there is no angle on the T and all you can see of the C is his fist raised for a foul.
As for the coach, he had a legitimate beef. But, if you are going to stomp out onto the floor you might as well just keep going to your locker room.
