See, when I read about stuff like you're commentating on..
It reminds me of the idiotic goalies who snap at players standing in front of them. I've taken more than my share of cheap shots from a 'tender for no reason other than being close to him, including several moves very similar to the checking the oil manuever that's been recommended.
I figure the second there are goalies bringing up idea's like this, then they're focusing on that at several points throughout the game, not just to protect themselves.
I've never ran a goalie. Have I made contact? Yup. Usually been thrown in by a defenseman, that's his problem, not mine. Do I dig at the puck and stand in front of you and make your life a living hell? Better believe it, but if you're one of those goalies who has to resort to chopping at the back of my legs and trying to sack me - well, you're pathetic, and I hope I play you because I always have more fun sliding the puck past you after you've tried some of that **** and giving a few choice words for your trouble.
