You don't have to be a hockey whiz to know that Wayne Gretzky holds a bushel of NHL records, including most goals (92) and points (215) in a season and in a career (894 goals, 2,857 points), or that the Montreal Canadiens have the most Stanley Cups (23 since the NHL was formed in 1917).
But there are a number of marks and standards that aren't nearly as well known -- and some of those, like the marks held by Gretzky and the Habs, figure to be around for a while.
Here are a few of the NHL's lesser-known records:
Best single-season power-play percentage: 1977-78 Montreal Canadiens
The 1970s and '80s were the golden days of power plays. It was not unusual to have multiple teams clicking at rates that would be unheard of today -- Nashville was tops in power-play percentage last season at 21.9, and no team in the last two decades has exceeded 26 percent.
The New York Islanders became the first team to convert on more than 30 percent of its power plays when they led the League with a 31.7-percent success rate in 1975-76. But that mark was topped two seasons later when the Montreal Canadiens turned 31.9 percent of their power-play chances into goals -- edging the Islanders, who converted at a 31.3-percent rate.
