Clark Gillies was a better enforcer than most on this list. And he could play/score as well. How was he missed?
“Jethro” Gillies was part of a long line of enforcers from Saskatchewan. Gillies played for the New York Islanders and the Buffalo Sabres during his 14-year NHL career (1974-1988).
Gillies' reputation as a formidable enforcer was already solid when he entered the NHL after playing for the Regina Pats in the Canadian Junior league. He racked up an impressive 570 penalty minutes in 201 games during his time with the Pats.
Gillies earned his bones protecting Mike Bossy and Bryan Trottier during the Islanders' 1980 Stanley Cup run. He famously battered legendary Boston Bruins enforcer Terry O’Reilly…and won…several times. His ability to protect star players was critical to the Islanders' four consecutive Stanley Cups."
