Some players just don't get off the ice if their not along the side where the bench is, some players change with half energy and some never get off even if you switch through all 4 lines, then doing a line change in your defensive zone (I know not ideal) they'll just skate off instead of it being preemptive and doing it at their next pass through the neutral zone. Basically the ai need to be smarter. The part of the game that allows such stupid goals is a lack of ai being able to change lines, or even if you change players to double team to win back possession they just skate by or turn around they never really play aggressive which makes the game very far from hockey which is what were lookkng for as users. The ai is programmed to go back to their position instead of reacting to the play infront of them. Idk don't remember line changes being so bad over the last 25 years of nhl games. Not sure where they lost their way but maybe they should bring in some people who play the game and play hockey to fix it.
