I'm not understanding your argument, are you implying they are worse off than last year? The sum of Panarin, Trouba, Kakko plus the additional year for Chytil, Howden, ADA and even Lias should be more than enough to cover the loss of production you're describing. I'm also not saying that these kids will all be superstars next year nor am I saying they will hoist the trophy, but it's not some impossible feat for them to be 15-20 points better than last year which puts them on the cusp of the playoffs.
I am not implying anything. I am stating that as things stand right now, the team is not really all that much better than last year.
Their record last year was fattened by the loser point. Panarin and Trouba are great, but Kakko and Kravstov will not replace the production of Hayes and Zucc. If the Rangers trade one of Kreider or Buch, then the addition of Panarim will not be enough to mitigate the hit of loosing these 3 players. Chytil, Howden, ADA & Lias, we all hope take steps forward. But the chances of all 4 making gigantic strides is very low. Some will take much smaller steps forward than others. Prospects rarely develop at a liner pace. That is not even to account for what happens if some...gasp.....take steps backward.
Now let's bring in the defense. As of now, Staal and Shattenkirk have roles on the team. They have another year of depreciation. Let's say they are both gone, one way or the other. You now have Hajek and his 5 games of experience, Lindgren and his two and Fox with his none. 3 rookies manning a defense does not a solid defense make. They WILL have growing pains. They are not all going to instantly become NHL caliber d-men over night.
Goaltending? Henke is another year older. Georgiev showed promise but also had some mediocre stretches. How many times have young goalies taken steps backwards or worse yet, showed themselves to be flashes in the pan? Don't bring up Shesty please as he has never played in North America yet.
Nothing is impossible. And sure, the could be 20 points better. They could also be absolutely no better than last year as a whole. Which is what I currently see. Some things will be better, some remain the same, some worse. All in all, I do not see a team that is materially better than last year. Especially of one of Kredier or Buch goes.
