The better question is: When is the last time a coach has gone 5 years between Stanley Cups on the same team when he's lost talent every single year including 3 of their top 4 defensemen and replaced them with nothing.
It would be amazing how quickly Babcock would 'find his voice' if Holland got him some talent.
that's the thing, you need to always be bringing in fresh blood who are new and find his approach fresh to buy into the system. With Bowman, even his voice was likely getting a bit stale with the team, but then all of a sudden Holland gave him
Hasek
Robitaille
Hull
and a young talented rookie in Datsyuk
I'm not sure if there were others, but that's still 4 significant players.
The fresh new blood this season was
Samuelsson
Quincey (last trade deadline)
Brunner
Tootoo
possibly Tatar can be this year's datsyuk if he gets to stay in the lineup
for most part I think those players are all playing well under Babcock, the only real mistake I see, if we got a real talented player who could be healthy in the top 6 instead of Samuelsson, this team could be pretty dynamite still, though that would mean Tatar might not be the rookie in the lineup if that were the case
