I think you're slightly overstating the future of the Rangers.
From that list there isn't a single player that projects as a truly elite player in the league. Sure, maybe Buchnevich or someone can far exceed expectations, but banking on it to happen doesn't seem realistic. Teams don't win cups without an elite C or a dominant D core. They don't have a dominant D-core. They might, again, if Skjei and Mcillrath exceed expectations.
Their best prospect outside Buch and Skjei is. . . Adam Tambellini?
best prospect after skiej is probably kovacs or gropp besides the goalies. it's not like the rangers have busted drafting Mcilrath krieder miller lundqvist staal stepan fast and hrivk have all graduated from prospect status and are making an impact in the NHL. zucarello girardi hayes and now vesey were all signed for free without giving up assets. they don't get top 5 picks because the never finish near last and the one superstar they could have had, the siberian express who was putting up ovechkin/bure type stats in the KHL freaking dies. It sucks double because that is also the reason it made them leary of picking tarashenko. but you play the hand your dealt. they are drafting fine. as far as finding a superstar, they need to find a late pick who flys under the radar ala Lundqvist, UFA, or a big trade. but to say that they can't draft or have no future is just dead wrong, a majority of the team is 26 and under and the positions they are old at have replacements in the wings. as for the defense, i believe shattenkirk will be a ranger this off season. believe me, gorton knows what he is doing. he has done a good job so far. in jeff we trust. all while playing competitive hockey
