This team isn't that talented, that's a myth, since 2012-13 the core players have aged out of their prime years (Giroux can still score, but he's not a 1C anymore, can't match up against top centers like Couts), and the young players are, well, young, and none are elite. Couts and Ghost are the only players in their peak years. The team is more talented than it's been since 2011-12, but not nearly talented enough to overcome putrid goaltenders.
And the goalies have been putrid since last January.
There is some talent, there is more on the way, but they're still a marginal playoff team with average to below average goal tending, and a 85 point team with bad goal tending.
A miracle coach isn't going to turn this around, he may get a bounce back, but Berube did following Lavi, and Hakstol did following Berube - what we want is sustained success. And that requires reshaping the roster and working in the talent that's coming up through the system the next three years.
Fill out and revamp the roster, improve the goal tending, and the right coach could contend for a Cup by 2021-22. If it's done right, they should improve every season from marginal playoff team, to solid playoff team to SC favorite.
