An attribute that could be cool is shot location. Maybe high vs low, glove vs stick side, and that tendency to shoot somewhere would make it easier for some players to score on certain goalies if they are put in specific situations. Like if a guy who shoots low stick side won't score often against a goaltender who is good at the butterfly and cheats on his stick side, but would be able to score on a goaltender who is not as good at the butterfly or cheats to their glove side. This could also work if positional play was a factor, like where someone is on the ice at a given moment and how their shot gets to the net. Meaning angles would be way more important and would give coaches something to do. It has a lot of flaws, I know, but it still is a path that could be worth exploring if there was some attributes that could be added in some way.
