It was one of the many bad ideas Toronto Maple Leafs coach Mike Babcock had last year.
Now apparently their thinking of trying it with Matthews or Tavares on the PK.
It’s honestly hard to think of worse idea.
Penalty Killing
Penalty Killing is a weird thing in the NHL because if a player gets on the PK, he gets a reputation for good defense, but good defense and playing on the PK are two different things.
On the PK, Ron Hainsey and Roman Polak are half decent because their biggest detriment (their lack of speed) is largely negated.
