For sure. You can see it in his judgement calls too, like when to go for offensive rebounds or when to get back on defense.
I see the same kinds of benefits with Jaylen Brown playing competitive chess. He has a great feel for when to be patient and when to be aggressive, he also never seems to lose track of the shot clock.
You have to be pretty competitive to make it in the NBA and I bet lots of these guys are using lots of little things they picked up in other competitive endeavors.
And for some reason every shooter in the NBA seems to have a single digit golf handicap, so it can work the other way too apparently, as I doubt many of them started playing golf first.
