I am only talking about penalty shots being called during ordinary play - not the shootouts.
If a team gets a penalty shot, I think the players on the ice when the penalty shot was called should see their +/- affected if the PS results in a goal. I even think there should be assists handed out to the players setting up the prevented player.
Do you agree?
But in reality, only the PS scorer's +/- gets affected (and perhaps the goalie's). At least it seems that way according to the HSP files for the most recent seasons.
(Example: Defenceman makes a great opening pass, setting a teammate free. The teammate is hindered, resulting in a PS. Teammate scores. No +/- for anyone but the scorer (or?), and no assists for the setting up.)
Why does only the PS scorer (and the goalie) get their plus/minus affected?
Has it "always" been that way (for as long as +/- has been recorded)? What were/are the reasons?
The penalty shot scorer does not get a plus for his goal.
The goalscorer does get a plus for a penalty shot goal.
Here's an example from last season. The Rangers beat Toronto 2-0. They scored a goal at evenstrength in the 1st period, then Ryan Callahan scored on a PS in the second period. Final +/- numbers for the game show 6 Rangers at +1, and 5 Leafs at -1. Callahan is the extra +. http://www.hockey-reference.com/boxs...010300TOR.html
The only exception would be if the penalty shot was awarded to a team that was on the Power Play; then the player wouldn't get a +.
I remember an even more extreme example. Late March 2006 (don't have the exact date): Toronto defeated Pittsburgh 1-0. Chad Kilger scored on a penalty shot with 6:51 remaining. For the game, Kilger was +1, everybody else was zero.
