There are an infinite number of factors that can't be emulated. Why was Dave Lewis a terrible NHL head coach, he came from Detroit? The idea that you should just hire someone from a successful organization and they are the best candidate is a compete joke. Would I consider it a pro in the selection process? Yes. However, you would hope that Patrick and Ted would be able to identify if the candidate is good in their current position and is well suited as an AGM, etc. or if they have the vision and attibutes to be the GM. Being the guy that runs things is a lot different then being the second in command.
Let me help you: Dave Lewis wasn't a bad coach... he was the wrong coach, for the time period. DRW was a team in transition, and Lewis is not a development type coach.
If you'd paid attention, you'd know that Lewis was given the job because DRW were angry with Barry Smith. His crime: he took time off to coach a team in Sweden, against the wishes of the DRW. Hence, he was not promoted, and ended up in Phoenix.
Smith WAS and is, a development coach. In fact, my son played for his team one summer when my son did the DRW camp for kids (which he did twice, it was cool... he also did Cap's camp twice too). We got to know Barry well.
If Barry or Dave were here, they'd tell you that emulating proper structure is a MUST.
Hope this helped!
