Columbus is going to be a team to watch over the next 2 years, as they already with a solid young D prospect core that will likely finish low, and add another star prospect in the draft this summer unless they have a tremendous 2nd-year rebound. I said that about NJ last year and the year before about the Rags. You need to look beyond what is happening now to see the future.
If Isles do not improve their prospect pool this year, they will not be able to make the playoff in 2 years, with both NJ and Columbus improving considerably and Rags not declining anytime soon. Washington and the Pens will miss the playoff once their superstars slow down considerably in 2 years. However, the issue will be that Ottawa and Detroit will become too competitive for Isles for the wild card spot with many solid prospects already coming to their prime in 2 years. Carolina - not too sure about their direction as they are a bit similar to where Isles is now.
Honesty I do not see this as the year where this team can win the cup, just not with what they currently have, the lack of depth players who can impact plays enough to sustain a long playoff run. To land a big rental and give up lots of future pieces, will be too risky for the future of this organization.
Next season, if they do not do better, the team should go the route of retooling or rebuilding, only keeping the young core, top prospects, and solid D vets like Pelly and Pulock, and add solid prospects in all positions, from anywhere they can find them. The scouts need to do a better job identifying the right players in the European and USA markets.
