I agree, NHL experience as an assistant can be very important when becoming a head coach at the NHL level. I have been saying this is a dangerous hire because of Chayka's inexperience in evaluating coaches. Hiring a coach with NHL experience is more expensive but takes some risk off the table. I don't care who they hire, I'll be supportive and hope for the best.
While NHL experience may be wonderful, I think with the team we have, that a younger "less experienced" coach may be fine. The problem with established "veteran" coaches is that they are used to having a more balanced team (veterans, mid-career, and youngsters). If we define veterans as having 410+ games (approximately 5 season's worth of regular season games played) , Mid-career as having 246-410 games (roughly 3 season's worth of GP), and youngsters as having 0-245 games played:

Goalies:

With the above in mind, I'd say that more extensive AHL experience would prove a more beneficial fit for the team. Of course, it's still important to have an Assistant Coach with more extensive NHL experience (assistant coach experience would be fine here). Ideally, I'd like to see a HC with quite a bit of AHL experience, an AC with more "veteran" NHL experience, and perhaps the second AC with extensive college (or juniors) experience. That way, all bases would be covered...
