Stamina drain is broken

How does stamina work in this game? In EASHL for example, say you get hemmed in your zone, your team loses stamina, but you do everything right defensively, eventually force a turnover and get out of your zone… only to have whatever stamina you had remaining, dissipate back to zero before you hit the red line. Instead of being rewarded for getting the puck out of your zone, the game punishes you. Now because you have zero stamina and you’re slow, you make a pass to a teammate, but you get laid out by somebody with Truculence in the neutral zone 5 seconds late and your teammate gets laid out just as he receives the pass, and before either of you can stand back up the other team has scored on a breakaway. I have 90 endurance on my class, but I run out of stamina like I have emphysema. Are there specific x factors that drain your opponent’s stamina? Make it make sense.
