Speaking to reporters on Wednesday, Boston Celtics rookie center Robert Williams said that Celtics head coach Brad Stevens “is one of the most hands-on coaches [he’s] ever worked with.”

Rob Williams: "(Stevens) is one of the most hands on coaches I’ve ever worked with. … If you have a question for him, his office is always open as far as basketball and off the court." — Tom Westerholm (@Tom_NBA) September 5, 2018

Williams assessment of Stevens only lends credence to the idea that he’s one of the best coaches in the league not just because he’s a masterful tactician but because, on a personal level, he’s a guy you want to go to battle for.

Kyrie Irving is stimulated by his intellect. Players, like Jaylen Brown, regularly call him “Brad” despite their youth because he doesn’t take himself too seriously.

Stevens refuses to make himself the talk of the town despite league-wide acknowledgment that he’s one of the best coaches in the league because he believes that the players deserve the credit.

The Celtics even have a head coach that’ll hop on an exercise bike with their rookie.
