It seems strange to me. I can only assume team's win games by having the puck more.
No teams win games by scoring more. There are no points for puck possession.
If you were to say your odds to score are better if you have the puck more you would be correct, in a sense. But simply having the puck more would not mean you will win, just increase odds.
What would be far more important would be shot quality. 10 bad angle shots don't really give you the best chance to score, and I would personally take 3 in the slot over a bad angle. Yes any puck can go in, but if we are going by odds, High Quality >>>>>>> Low Quality in terms of shooting %
