Celtics coach Brad Stevens dunks off trampoline

BOSTON -- Air Brad?

Boston Celtics mascot -- and expert trampoline dunker -- Lucky the Leprechaun (Kit Ackerman) posted a video to his Instagram account Sunday showing Celtics coach Brad Stevens dunking off a trampoline at the team's practice facility.

So how did it come about?

"Actually, I was there just rebounding for Brady yesterday for a little bit. Brady’s my 10-year-old, and I just looked down the side of the court, and they had those trampolines set up," Stevens explained Monday night before his team hosted the Utah Jazz. "I thought that would be fun, so I asked Lucky how to do it.

"I did ask that nobody tape it but obviously that got lost in translation. It’s proof I need to communicate a little bit better, but luckily the few tries before that didn’t make it on the web because it wasn’t quite as pretty."

Stevens was asked what score he might give his dunk.

"Hey, it went in," deadpanned Stevens. "Brady would give me a 10, so I’m in. A dunk for me is pretty unusual, so I enjoyed it. It was fun."

Asked if he ever dunked during his high school or college playing days, Stevens said, "Did I ever dunk for real? Nah, not with -- no. Everybody that’s played says they’ve dunked and they have at some point but it’s with a flat ball and a 9-foot-5 rim, and different -- I’ve done that."
