By now, most basketball fans who have bothered to pay attention know that former Warriors coach Don Nelson is no longer the intense, boisterous figure who stalked NBA sidelines for more than three decades.

Nope, at 79, he’s a laid-back dude living in Maui who wears his long silver hair in a pony tail, grows and smokes weed and plays a ton of poker with Willie Nelson and other celebrity pals.

On Tuesday’s (June 25) edition of “Real Sports With Bryant Gumbel” (10 p.m., HBO), the show’s host catches up with Nelson in paradise to get a feel for his oh-so-chill, post-NBA lifestyle.

The segment recalls his NBA playing and coaching days (he still roots for the Warriors) and covers much of the same ground that a 2018 New York Times profile did, including the fact that Nelson has reconnected with a daughter — Lee Anderson — he had out of wedlock during his playing days. Until she wrote Nelson a letter when he was coaching the Dallas Mavericks, he went nearly 30 years without knowing she existed.

Anderson was the result of a weekend fling Nelson had with a flight attendant. As Gumbel so acutely concludes, Nellie was “quite a player on and off the court.”

Here’s a sampling of what Nelson addresses during the “Real Sports” segment:

— On the care and nurturing that goes into cultivating a vast marijuana farm: “You gotta treat it like a baby. You gotta water ’em. You gotta have music for ’em. You gotta bless ’em when you go in. It’s a whole process, I’m telling you.”

— On the night a friend, Greg Booth, died while playing poker in Nelson’s man cave: “He died right there — right in front of us,” he says, pointing to the poker table. “And the guys said, ‘What should we do, Nellie?’ I said, ‘He would want you guys to play.”

And so they did — until the coroner arrived.

— On his own mortality: Nelson admits that he thinks more about death the older he gets. “Does it scare you?” Gumbel wonders. “No,” Nellie replies. “I’m ready to go right now.”

— On the surprise letter he received from Anderson: “… I almost s— myself. Can you imagine?”

— On his reaction upon meeting her at the airport: “I have the same emotions today as I had then,” Nelson says his voice cracking and eyes misting up. “I was excited. I knew she was mine. Absolutely.”

(Anderson, who now lives next door to Nelson and his wife, Joy, appears in the program and calls her birth father “the most gracious, kind, giving … warm and tender” man.)
