George Karl was summoned by DeMarcus Cousins and Rajon Rondo last week for a meeting.

This was supposed to be a 15-minute discussion but instead became a positive two-hour meeting.

“It was a powerful meeting for all three of us,” Rondo told Yahoo Sports.

Rondo and Cousins were also able to get some lingering frustrations off their chest, and Karl offered back his thoughts.

“We asked him to just sit with us so we can pick his brain and share our thoughts,” Rondo told Yahoo Sports. “What I love about [Karl] is he’s very open. George is not a dictator. ‘What can we do positively? What can we do to improve?’

“If you can come into a meeting with no egos and everyone was humble, it just works out for the better.”

Rondo and Cousins told Karl they thought his film sessions would be better with more constructive criticism and teaching.

Rondo and Cousins said they also told Karl not to hesitate to use them as examples in film sessions.

“I told him to start with me. Whatever I can do to help the team,” Rondo told Yahoo Sports. “If you have to bully me or call me out, I can accept that. I’m a 10-year vet. I learned from [former Boston Celtics coach] Doc [Rivers] and the past guys that it has to start with the vets who have the most leeway on the team or the most responsibility.

“[Cousins and I] are both trying to change the culture, change the organization.”
