No, he didn't have a brother named George! A graduate of the Calgary Centennials and a Los Angeles draft choice, Carlins career wasn't particularly eventful, though he did score an NHL goal and not everyone can say that.
Carlin was drafted by the Kings, 86th overall in 1970, and promptly registered 100 points in his final year of junior with Medicine Hat. But the year after he played just five games for the Kings and the rest of the year in the minors.
Not content, he took his act to the WHA, but a year later he was back in Alberta playing senior hockey in Calgary. He retired altogether in 1977.
