How can a hockey player get a minus 1 when he scores 5 points and the opposing team scored only 3 goals in total?
Goals scored on the power play do not count as a +1 (although
goals given up on the power play, shorthanded, count as a -1).
So, theoretically, if three of the five points were scored on
the power play and he was on the ice when all three goals were
scored against he would be a -1. (+2 - 3 = -1)
