Sather's method is the laziest form of managing a hockey team there is. Let other teams draft, develop and find success with players (either through Stanley Cup wins or at least becoming stars), then sign them July 1st to come to NY and win nothing.
His plan--if it can even be called one--is to add the biggest name available. That's it. Big name from last year not working out? Get this year's.
Gaborik needs help scoring, add Nash.
Gaborik not scoring enough, trade Gaborik.
Nash needs help scoring, add St. Louis.
Nash not scoring enough...
The revolving door means no group of Rangers core players ever stays together for more than a few seasons. Smart, patient GMs understand that the best way to build a team that can contend for a number of consecutive years is to assemble a core group (mostly through the draft but some trades/signings can be involved) that you stick with. The Blackhawks will be contenders as long as Toews, Kane, Keith, Seabrook and Crawford are there. LA has Kopitar, Carter, Wiliams, Doughty and Quick. They're not going to win the Cup every year, but Bowman and Lombardi don't trade core, star players if they don't win it all one year. The days of dynasties are gone in a salary capped NHL. If you really have a good group that can be successful in the playoffs they're going to be in the mix again next year. They have faith in their players and are loyal, but also wise enough to make adjustments to the roster when needed.
Will this current Rangers' group be together a few years from now when those other contending teams are still intact? Probably not since the Rangers under Sather can not keep a group of players who are young or in their primes together for any substantial length of time. Are St. Louis and Richards going to be on the Rangers two years from now, or even one year from now?
How many skaters on this current team would you have faith in going forward as players who can be difference makers in the playoffs for the next 3-5 years and help you win a Stanley Cup?
McDonagh, Girardi and Staal are a good start on the defensive side. But the forward group is lacking. Stepan, the team's #1 center, wilts in the playoffs. Zuccarello, Pouliot and Brassard look better than they really are because Nash, Richards and St. Louis have been disappointing. Kreider has a small sample size but shows promise.
The offensive problems are compounded by the fact that these forwards, as a group, are not strong enough defensively or physically to be effective players in the playoffs when their offense disappears. If Nash played with the tenacity, physicality or defensive awareness that players like Dubinsky, Callahan and Anisimov did then his goal-scoring failures wouldn't be so amplified.
