You could be right. There is something to be said of those that can find success wherever they go. Though I think a good GM/Coach tandem is a lot more beneficial to a team. If a GM knows the kind of players a coach needs for his system it makes finding and developing those players easier. Dubas and Keefe are a similar tandem to Yzerman and Cooper. Dubas and Yzerman draft the kinds of players they like and the coach is able to fit those players into their system better rather then trying to fit round holes in square pegs.
I agree with the philosophy but hard to pull off when you are looking 4 years out on the players you draft. Coaches usually only last around 5 years not enough time to fully go through the cycle.
In case of Chevy and Moe to me it appears that they are not fully on the same page. Chevy has gone for a lot of skill whereas Maurice favors size and grit. Maybe that is changing however with recent drafts with guys like Ves, Stanley and Gustovson. All seem very much Maurice types.
