I'm quite sure it was Al Secord in 1983.
There is a point for a goal and assists. There are two assists awarded in hockey for the last two people (on the same team as the scorer) to touch the puck, given the other team did not gain posession in the time between when the scorers teammates had the puck and the scorer scored the goal.
The leading scorer in the 2010/11 season was Daniel Sedin of the Vancouver Canucks with 104 points. Corey Perry of the Anaheim Ducks was the leading goal scorer with 50.
Wayne Gretzky passed Gordie Howes as NHL's all time top scorer.
a point is a goal or an assist. You get an assist if you pass the puck to the goal scorer (1st assist) or pass to the person who passes to the goal scorer (2nd assist). All goals and assists count as one point. For the NHL, most goals is the tie breaker for the Art Ross trophy given to the player with the most points.
Paul Coffey hold this record with 48 goals on 1985-86 Nhl season. Bobby Orr the 2nd 46 goals on 1974-75 Nhl season. Any other NHL defenseman can't reach the 40th goal/season.
Outside of some fantasy-league scoring systems and the NHL's recently-introduced "shoot-out" format, a goal has always been worth exactly one goal (and one point in the goal scorer's point total).
