This thread is a joke but ya that video is brutal. Slewfoot against the board is ok apparently.
Is it a slew foot a clip or a trip?
Rule 44 - Clipping

A player may not deliver a check in a “clipping” manner, nor lower his own body position to deliver a check on or below an opponent’s knees. An illegal “low hit” is a check that is delivered by a player who may or may not have both skates on the ice, with his sole intent to check the opponent in the area of his knees. A player may not lower his body position to deliver a check to an opponent’s knees.

Rule 57 – Tripping
57.1 Tripping – A player shall not place the stick, knee, foot, arm, hand or elbow in such a manner that causes his opponent to trip or fall. Accidental trips which occur simultaneously with a completed play will not be penalized. Accidental trips occurring simultaneously with or after a stoppage of play will not be penalized.
