I lost interest I the NBA also, but it wasn’t because all those Celtic legends left, it was because players like Kareem, Wilt, Magic, West, Baylor and a few other great Lakers left. Those days when the Celtic and the Laker Greats played each other for all the Marbles are gone forever.
The Lakers vs Celtics vs Pistons vs Bulls were the best of NBA ever, I think never to be replaced
