My thoughts on Cronin based upon other comments on this board.
1 - Maybe he'll be the next Scotty Bowman, maybe he'll be the next Dallas Eakins. Time will tell.
2 - Cronin being 60 years old is completely irrelevant as to whether he'll be a good coach or not. Irrelevant.
3 - The fact that he's a first-year NHL head coach is notable, but only indicates his lack of time-tested experience. I'm more interested in his potential, his ability to inspire the players and if he'll improve morale (which in my opinion is the most severely underrated facet of ANY organization). Time will tell.
4 - As established, experienced coaches retire or sabotage their careers (Babcock), new inexperienced coaches have to take their place. That's just the way it works. See line 1.
5 - He came from an organization with a winning culture. He probably has brought some of it with him...
6 - I wish the man good luck for the upcoming season! (Insert "he'll need it" jokes here...)
