It's curious that so many people are alleging nepotism and an "ol' boys club." Do they not realize that both Robitaille and Blake already held high-profile roles in the organization that made them next in line for each job? Robitaille was the team's President of Business Operations for the last 10 years and was ridiculously successful in that role. Doesn't that success entitle him to a promotion? As for Blake, while not nearly as entitled to a promotion, he was still Assistant GM of the Kings for the last 4 years and GM of their AHL affiliate (which won the Calder Cup under his management after he replaced coaches). Both men were next in line for their new jobs and did at least enough to be given the benefit of the doubt that they could handle more responsibility.
If you were going to allege nepotism and an "ol' boys club," it should've been done when Robitaille and Blake were first hired to their former roles in the organization, when both had no management experience and were gifted high profile jobs purely because they were franchise stars. Now, though, they've actually been successful in those jobs and given reason to wonder what they could do with more responsibility, so it's a little late to hold their playing careers against them. From all accounts, both men really impressed others in the organization with their aptitude for their former roles, so they weren't promoted because they were star players, but because their managerial talents were admired.
Specifically, the suggestion of "haven't they learned anything from Sakic/Roy in Colorado?" doesn't make much sense. Both Robitaille and Blake have had far more relevant experience (as outlined above, 10 years for Luc, 4 years for Rob) than Sakic had when he was hired. Also, neither has been hired to be coach. Maybe, if Blake hires Stephane Fiset to coach the Kings, the Sakic/Roy comparison might be more valid. Blake has said, himself, that he'd prefer a coach with NHL head coaching experience, so it doesn't sound like he has any intention of going the route that Sakic did by hiring Roy and Bednar. Also, his first managerial decision so far has been promoting Mike Futa to Assistant GM (happened literally while I was typing this post). Maybe he's smarter than people give him credit for. I'm willing to give him the benefit of the doubt and judge him by the moves that he makes, rather than by an example in another organization that may not be very relevant.
