This is brought up a lot when it comes to replacing old Bettman. Being commissioner entails more than ust giving awkward stuttering interviews and handing over the cup to a new team each summer. It's a high demand position requiring an educational background in law and labor relations. I don't think any former player except maybe Ken Dryden could make a crack at it.
Thing is it only has to involve law and labour relations in terms of hockey. Any career player and coach/gm/league official could do it as they've lived it. Plus there will be advisors for that stuff. I think it'll be good to have a commish who can provide a much needed link between hockey talent (players, coaches, etc), and hockey businessmen. Think how much smoother negotiations with the NHLPA would be if a former player was commish?
