This is exactly right. A good coach can be the difference between a first round exit and a third or taking a team over the hump into a champion who is really close or taking a borderline playoff team into a playoff team. Mike Babcock isn't going to turn Buffalo, Edmonton, Toronto, etc into a cup winner next year, but he will make them better and he will help their young talent grow. and I think Babcock is smart enough to realize that, so when he is being courted by these teams they are going to need to lay out a legit plan for him as to where they expect to be in 3-5 years and what they are doing to get there.
That thought process, IMO, is exactly what has him questioning staying in Detroit, because 3-5 years from now in Detroit is questionable with losing Datsyuk and Zetterberg and there has yet to be a couple standout prospects in the system to replace them. Dylan Larkin may be the guy, but that is yet to be seen at a professional level. Because everything else that he seemingly wants is there in Detroit, good owners, a good relationship with management, a culture of winning, an owner willing to spend, his family enjoys it there, etc.
