MacGregor was drafted by both the
National Hockey League (NHL) and
World Hockey Association (WHA) in 1974 and chose the WHA. He had a superb rookie season in 1974–75 with the
Chicago Cougars, averaging nearly one point per game. But his productivity dropped sharply for the remainder of his pro career with the Cougars,
Denver Spurs,
Ottawa Civics,
Cleveland Crusaders,
New England Whalers,
Indianapolis Racers, and
Edmonton Oilers. MacGregor also played in Europe. ==Personal life==
