Magic Johnson’s blustery tenure as president of the Los Angeles Lakers has ended with a bang.
The charismatic five-time NBA champion promised to deliver superstars to Southern California and return the Lakers to greatness, but he ended up shocking the basketball world by resigning his position in an impromptu gathering with media members that lasted more than 40 minutes before the regular-season finale against the Portland Trail Blazers.

Johnson, who announced he was HIV positive in 1991, said his health was ‘‘wonderful’’ and was not a factor in his decision. The business mogul and Los Angeles Dodgers co-owner sounded relieved while delivering the news, noting that he was going to return to his other interests and wanted to set up the Lakers for what will be a busy summer.

‘‘If I’m going to step down from the Lakers, this is the best time,’’ Johnson said. ‘‘The draft is not here. Free agency is coming up. Somebody can be in here to recruit … I’m looking forward to my life. I want to go back to being a businessman and helping the black community and the Latino community. I get to go relax and watch my Dodgers …

‘‘I want to be me. I knew if I stayed in the role, I’d be giving up a lot of me.’’
