|only one player should've gotten the lifetime ban for being a sore loser and just plain dumb becuase the other guy was probally just defending himself|
Having reffed a chunk, myself, I can say that you find out pretty quick who's defending himself, and who's being a poor sport and/or fighting back.
Buddy lights up the guy walking off the field.. he's asking for a poor sportsmanship penalty.
Guy he shoots comes over, drops his gear, and assaults another player? That's lifetime ban, immediately, and likely assault charges filed with the police, too.
Buddy who shot him in the first place drops and covers up? That's defense. If he stands his ground and starts trading knuckles with the guy he shot up? Buddy's just as guilty as the guy who's offering him lumps.
*shrug* That's just me, though. I'm no NXL ref, I've just reffed in smaller local and regional leagues.
