Brooklyn Nets players felt as though Kenny Atkinson lost a section of the locker room, reported Ian Begley and Corey Hersch of SNY.
Atkinson and the Nets agreed to part ways on Saturday morning.
Sean Marks said that Atkinson admitted to him that his voice wasn't resonating like it once did.
"There wasn't one game, an event of games (that led to the firing). This was a culmination of events over the course of the year. Kenny is brutally honest, and the humility he showed to say he'll admit, 'My voice is not what it once was here. It's time' (was remarkable)," said Marks.
Marks added that discussions over Atkinson's future had been on-going over the past couple months.
"It was after deliberation with Kenny over the course of the last two or three months. They were ongoing. I can't really put a time on it. We decided that if there was an opportunity for a change and put the Nets in a better place, whether that was personnel on the court or any one of us, we would have that honest conversation."
