Greig played 41 total games in major junior hockey with the Medicine Hat Tigers and the Vancouver Nats in the WCHL in the 1971–72 and 1972-73 seasons, respectively. Although he was a fairly skilled player, he was relegated to the role of an enforcer, primarily due to his weight and size, something which was coveted by professional teams during this era of the "Big Bad Bruins" and the "Broad Street Bullies". However, there were many young enforcers coming up through the junior ranks during this period, and as a result Greig was selected 114th overall (8th round) of the 1973 NHL Amateur Draft by the California Golden Seals, and 111th overall in round #9 in the 1973 WHA Amateur Draft by the upstart Cleveland Crusaders, both, not overly high draft placings.
After being cut from the Seals 1973 training camp, Greig chose to quit hockey and focus on other pursuits. However, he was called by the Seals organization during the mid 1973-74 season, and surprisingly was asked if he would report back to the Seals for a roster position for the remainder of the year. At the time, the Seals did not have a dedicated "enforcer", with the exception of skilled younger players such as Seals' rookie defenseman George Pesut who would occasionally step up and fill the role and protect teammates when necessary. However, for the skilled players, it was not deemed to be their role, and injuries were imminent. Consequently, the Seals were in need of a player with Greig's credentials and size. Greig accepted the Seals' offer and contract and joined the team in his new role. However, due to his lack of game shape at the time, he only played one game in the NHL for California in the '73-'74 season. On a conditioning stint, Greig then spent the remainder of the season (13 games) with the Seals' minor league team, the Salt Lake Golden Eagles. The following season in 1974-'75, Greig played a total of 8 games for the Seals, accumulating 1 point, and 42 minutes in penalties, before being benched and sitting out the remainder of the season. The following year seemed to signal his decline in pro hockey, as he managed 10 games with the lowly Flint Generals in the International Hockey League and 1 game with the Seals main farm team, the Salt Lake Golden Eagles in the '75-'76 season. He recorded 5 assists and 88 minutes in penalties while playing in the minors. However, in the '76-'77 season, interest was rekindled in the form of the World Hockey Association's Calgary Cowboys, who signed Greig for his fighting prowess. He played in 7 games for the Cowboys, and split the season playing for their minor league affiliate the Greensboro Generals. Following two seasons saw Greig traded to the Cincinnati Stingers and Indianapolis Racers which had the likes of eventual superstar Wayne Gretzky and high scoring Blaine Stoughton on the roster. Greig played in another 53 games in the WHA, and in the years to follow, Greig played in numerous leagues and for a variety of semi-pro teams before deciding in 1985 that his hockey career had come to an end.
After retiring from hockey Greig turned his exploits to powerlifting. He holds several Canadian powerlifting records, and eventually became president of the Canadian Powerlifting Council. He owned and operated a gym in Okotoks, Alberta with his wife, Wendy.[1] He was the brother of NHL hockey player Mark Greig and the uncle of NHL prospect Ridly Greig.
