The line of Don Murdoch, Greg Carroll, and Morris Lukowich was unstoppable in Medicine Hat, yet all three ended up having remarkably different pro careers. Lukowich had a fine career with Winnipeg, Murdoch had a decent stint with the Rangers, but Carroll simply couldn't find the range in the NHL.
Although he was drafted by Washington in 1976, he chose to start his pro hockey life in the WHA (as did Lukowich), and moved on to the Caps two years later. In the WHA he had back-to-back 15-goal seasons after a 60-goaal year with Medicine Hat, a drop in production that proved his undoing.
Carroll played with three teams in two partial seasons, going from the Caps to Detroit to Hartford in less than a year. He scored just 20 goals in 131 games, numbers that might have been fine for another type of player, but no for one who showed such remarkable offensive skills in junior.
Carroll retired in 1980 after playing a few games in the AHL.
