Warden of the North
Ned Stark's head
Are you suggesting that since the Leafs are gifted offensively but a black hole defensively that Carlyle needs to play a system more like Ron Wilson pond hockey instead of a defensive system because of the current players preferred style? . That is what my impression was based on what you posted originally.
It appears from Carlyle's comments recently he wants more blocked shots by everyone, more diligent backchecking, and taking a hit to make a play to clear the zone is trying to get his team to defend better, and cut down on scoring changes against. It seems Carlyle is saying the right things that convinced Shanny to extend him and he will get his players to be more accountable away from the puck to get better results with this roster.
Shanahan's comments (posted above) about giving up too many shots against and by extension too many goals against is a sign of a problem and that players and the coach looking in the mirror to tighten up defensively.
I think Randy needs to drop the "swarm" style defense and go for a more traditional, proven style. New assistants will help in this regard.
