In 1985, the Lakers got revenge, beating the Celtics in six games. In 1987, the rivals clashed again. During a Game 4 Lakers win in the Garden, Nicholson absorbed the crowd’s razzing and motioned for more. Is that all you got? The next day Nicholson arrived at the Garden to watch Lakers practice. Boston Globe columnist Leigh Montville introduced himself. Nicholson didn’t do many interviews, but he sat and talked with Montville for 15 minutes. Other reporters joined in. Nicholson discussed his respect for the Celtics, and what it was like to be Public Enemy No. 1 in a sea of green. “They’ve got a lot of ‘Bleep you, Jack,’ signs up,” Nicholson said of the Boston crowd. “I do invite it but I think ultimately it hurts them. … You can’t afford to let one fan take this whole building out of the game.”
