Magic Johnson accuses Los Angeles Lakers GM Rob Pelinka of betrayal weeks after resigning

Magic Johnson on Monday accused Los Angeles Lakers’ general manager Rob Pelinka of betraying him before Johnson's surprise decision last month to step down as the team’s president of basketball operations.

Johnson appeared on ESPN’s “First Take” to discuss what led to his stunning departure in April. He said he was tired of all the “backstabbing” going on in the organization and some people were telling him Pelinka was talking about Johnson behind his back.

“If you're going to talk betrayal, it's only with Rob,” Johnson said. “But, again, I had to look inside myself. I had been doing that for months. Because I didn't like that Tim Harris [Lakers executive] was too involved in basketball. He's supposed to run the Laker business, but he was trying to come over to our side. Jeanie [Buss has] gotta stop that. You gotta stop people from having those voices.”

Then, Johnson said, he started to hear rumors that he wasn’t “working hard enough.”

“Things got going in the right direction, and then I start hearing, you know, 'Magic, you're not working hard enough. Magic's not in the office,'" Johnson said. "So people around the Laker office was telling me Rob was saying things -- Rob Pelinka -- and I didn't like those things being said behind my back, that I wasn't in office enough and so on and on."

He added: “So I start getting calls from my friends outside of basketball saying those things now were said to them outside of basketball. Now not just in the Laker office anymore, now it's in the media and so on.”

Johnson said the final straw came during the firing of coach Luke Walton. Johnson said he wanted to fire Walton, but then realized he didn’t have the power he thought he had to fire him.

“…I told them, ‘When it's not fun for me, when I think that I don't have the decision-making power that I thought I had, then I gotta step aside,’” Johnson said.

Lakers star LeBron James revealed on his TV show earlier this month that he learned Johnson was leaving through a friend -- not from Johnson himself, something the basketball great also talked about Monday.

“I respect LeBron for what he just said,” Johnson said. “I love LeBron, I love his family...but sometimes as a man, you have to make decisions based on your well-being. And I made that decision.”

The Lakers, have won 16 NBA championships, second only to the archrival Boston Celtics, but have not made the playoffs since 2013. Johnson won five titles with the Lakers in the 1980s before retiring abruptly in 1991, when he announced he had contracted HIV. He returned to coach the team for 16 games during the 1993-94 season and played in 32 games during the 1995-96 season, largely off the bench.

Johnson has enjoyed a prosperous post-playing career, with many business interests along with ownership stakes in the Los Angeles Dodgers and Los Angeles FC.
