While there are still dirty slewfoots, they were obvious and seldom occurred. The last couple of years the call is way more common and many don't fit the reason the rule was enacted. By definition a opposing players must swipe out the leg of the player while using elbow or arm on in an opposite direction on upper body to take the legs out. Belchetz leg was behind but no arm or elbow pulling back. Slewfootvcalks used to occur in a open ice area, not when a player is trying to avoid a hit while his legs are pinned by checking player against the boards. I'd call that a soft call if it waz s Sarnia player with the infraction. Refs decision. They all differ in opinion
