Didn't see that anybody mentioned it, apologies if so, but if you watch the video closely, you'll notice that the father is in the middle of trash talking a C's fan while Davis bumps into his son. This guy is a real piece of work.
His broken logic pertaining to players going out of bounds:
"If I cross that line, the NBA will take away my tickets. It's a double standard."
