Or maybe they are both wrong. Or maybe the line combinations aren't working regardless of what they are. Maybe the players are just the wrong players.
We can't go from failing with Babs, and then failing with Keefe and being like "Oh, maybe Babs was actually right" when his way was also failing but just further in the past, so its not top-of-mind.
IMO I think they should go with Willy/Matthews, and Marner/JT. Maybe it spreads it out better. All I know is nothing has worked in the last 5 years in the playoffs, regardless who was coaching.
