In my ball hockey league, there are a few fuckfaces who run you, who slash and check and trip. It's a joke league, really just organized pick up with nothing on the line, so it's ridiculous that they play like that because they do hurt you once in a while. But it's because of that, when I've got the puck and one of them is barreling towards me or chasing me down, as much as I'm thinking about the puck, I'm also concerned about whether they're going to trip me, push me forward while I'm running (which results in a hard fall), collide into me, etc. - ALL of which has happened, many times. It gets into your head and makes you rush, or make a bad play, or fucking pay the price and get hurt for nothing. Basically the Cliffy hit from Game 1.
We need a guy or two who can make clean hits like that, and regularly during a game, that crush the opponent and have them thinking twice about what they're going to do when they're in the vicinity.
