Kastelic was out there for one reason, in the dying seconds of a game that was already over. He just took a run at Lilleberg right before this, then you see him look up at the clock and decide to do it again with a few seconds left. The kid wasn't going to let that slide and protected himself. Yeah he catches him high but the stick rode up a bit too, heavy dose of hockey karma right here.
Nothing wrong with playing until the end but you have to live with the consequences if you decide to go that way. Next thing you know he's being helped off the ice by 5 people, safe to say that backfired horribly. Lilleberg has no fighting background overseas and he's learning on the job against some tough players, can't blame him at all.
Tuesday in Boston could get wild.
