People are obsessed with irrelevant celebrities, but not Boston Celtics head coach Joe Mazzulla.

It's a breath of fresh air when someone of prominence just diminishes people who just aren't important, when you look at them closer.

Mazzulla did just that after Prince William and Kate Middleton took in a courtside game, dismissing their royalty and showcasing his reverence for his faith.

How does Prince William really impact or help you?

He doesn't.
