Honestly, I think it boils down to two things.
1. Can Keith, Seabrook and Hjalmarsson play defense like they did last year?
2. Can Kopecky, Brouwer or anyone else step up and get in Luongo's grill?
Those two questions will answer if the Blackhawks can compete.... IMO.
Re: 1. Crawford isn't going to be winning many games for us. He is okay, but that is it. Can we play swarming/shot blocking defense like we did last year, to take the pressure off the goalie? I could include Leddy, Campoli, Campbell, etc., but the top 3 D need to step up and provide leadership for the rest.
Re: 2. Obviously, Buff was amazing against Vancouver in the past 2 playoffs. That is the past but it provides a blueprint on beating Luo. We don't need a screener to score, but we need someone to screen him. We have plenty of guys who can score on him, but the screen is necessary, or else he is a really good goalie. I think, after the past two postseasons, that Blackhawks fans laugh at Luongo's talent. It's legit, he just has a weakness that the Hawks have exploited the past 2 seasons. If we don't go at him with a screener, then we will be playing into his strengths.
