I used to challenge a friend to stun gun duels when I was drunk, he said he'd only do it if he got to tase me for a while first to make sure it was safe, which I was just barely not-dumb-enough to refuse.
So I assume "trained professionals" are guys who have been tased before and didn't die.
Seems like a pretty desperate attempt to insert an electrocuting device into some sort of sport.
Stars for the douchebags they show playing this, use of epic choir music and already giving it an acronym.
The ball ruins it, because it makes it about something besides guys tasering each other. Maybe they need a Designated Stunner rule, each team has someone who can't touch the ball but gets to use a cattle prod.
