Junior Bridgeman, who followed a strong N.B.A. career with a remarkable run as an entrepreneur, acquiring hundreds of fast-food restaurants, a Coca-Cola bottling business and a minority stake in the Milwaukee Bucks, his team for a decade, died on Tuesday in Louisville, Ky. He was 71.

The cause was a cardiac event, a family spokesman said. Mr. Bridgeman had been talking to a reporter for a local television station during a charity event at the Galt House Hotel when he said he felt that he was having a heart attack, the spokesman said, and he was taken to a hospital, where he died.

Mr. Bridgeman’s business success brought him a net worth of $1.4 billion this year, Forbes magazine said, putting him in “rare air alongside Michael Jordan, Magic Johnson and LeBron James as the only N.B.A. players with 10-figure fortunes.”

Mr. Johnson, writing on X after the death, recalled that Mr. Bridgeman, a former small forward, had “one of the sweetest jump shots in the N.B.A.” Mr. Bridgeman, he added, had helped create a blueprint for “so many current and former athletes across sports that success doesn’t end when you’re done playing.”

Mr. Bridgeman was not a major star during his 12 seasons in the N.B.A., 10 with the Bucks and two with the Los Angeles Clippers. But he stood out as a sixth man who provided a scoring boost off the bench for a Milwaukee team that largely excelled under Coach Don Nelson. From 1975 to 1987, Mr. Bridgeman averaged 13.6 points a game.
