I think a way you can penalize speed and agility without effecting other stats, because lets face it our players rating wise are too low across the board, is to do two things.
1. Hustling down the ice in any fashion BURNS through your energy quickly.
2. Hard turns and stops cost energy to perform.
These two changes could slow the game down immensely and make it less a rush style and a little more tactical.
Oh and my usual add some form of line change/energy regen system to balance this so if you use all that energy you can, at the risk of being out of position, go to the bench to refill your energy back to full.
