Linemates staying motionless is one of the biggest reasons I think guys get tossed out of faceoffs. I also think it's one of the "rules" that gets overlooked the most. We see guys jostling for position all the time on draws.
One question I have, which is sort of related: (I haven't heard this in a while, so maybe I'm making it up, but...) I used to hear commentators talk about intentionally getting kicked out of the draw. Why would someone want to get intentionally kicked from the draw? (Or am I making that shit up?)
