Detroit Pistons incoming third year power forward Henry Ellenson had the summer of his life. Not only was he able tow work on one of the most important facets of his game, but he was also able to do so under the tutelage of an NBA great.

The 21-year-old spoke to James L. Edwards III of The Athletic, and shared how he used the offseason to focus on developing his shooting.

“For me, continuing to work on, obviously, always shooting,” Ellenson claims. “Getting a lot of shots up.”

In his first two years with the Pistons, Ellenson averaged only 3.6 shots per ballgame in 8.2 minutes off the bench. Entering perhaps the most important season of his young NBA career (his rookie deal stipulates that next season will be a team option), the former Marquette standout is definitely looking to make his mark for the team.

Lucky for him, he chanced upon Boston Celtics legend Kevin Garnett during a team practice session.

“I was working out with Blake (Griffin) right away, and KG called me over from across the court,” recalls Ellenson. “I went over there and he was like, ‘I’ve been watching you play during Summer League, and I like your game a lot.' He was like, ‘I want to work on some things with you.' I said, ‘Yeah, of course.' It was cool because, I didn’t expect that I was going to work out with him. Being able to learn from him, because he’s going to be a Hall of Famer, was pretty cool.”

Being given the time of day by a one of the best power forwards of all time is certainly an extraordinary opportunity. This will go a long way for Ellenson, and hopefully, it turns out to be the extra push he needed to take his game to the next level.
