"In 1988/89, teams averaged 299.3 total goals for, each. Let's call it 300. Of those goals, 84.3 were on the powerplay, call it 84. 12.2 (so 12) were shorthanded. 8 goals were scored on penalty shots this season, for a total of about 0.4 per team for the season. In 92/93, 136 empty net goals were scored league-wide. It took me longer than 60 seconds to find this stat, so that's as close as we will get to 88/89 for this exercise and we will consider it to be accurate. That means 6.5 empty net goals for per team, which is definitely lower than it is today. Anyway:
300 total goals scored per team
84 power play goals scored per team
0.4 penalty shot goals scored per team
12 shorthanded goals scored per team
6.5 empty net goals scored per team
Adding these up -> 197 even strength goals scored per team
Dividing this by 18 skaters per team per game, and 80 games each:
0.06 power play goals per player per game
0.0003 penalty shot goals per player per game
0.008 short handed goals per player per game
0.005 empty net goals per player per game
0.14 even strength goals per player per game
Thus, the odds of getting all five in the same game:
0.06 x 0.0003 x 0.008 x 0.005 x 0.14 = 0.000000000008, or a 0.0000000008% chance of happening. Converted to a fraction, this is about 1 in 1,250,000,000 for the average Joe. Yeah. Never happening again."
It is just so incredibly rare that it might never happen again. 10 points seems more doable.. eventually.
