Its fair to not be sold on the team as currently constructed, because i agree that right now they are over reliant on Igor & the Powerplay. However, given the cap space we currently have, and the fact that its going to be gone this summer, we should be adding at the deadline, even if its for rentals. No one is saying to gut the farm this year, but trading some pieces in the mold of draft picks, Kravtsov, Chytil, one of Lundkvist/Jones (not all, just some - dont want this to be taken out of context), for immediate help (top 6 FWD, top 9 FWD, more reliable 3rd pair D) isn't going to hamstring them, and will very likely improve their 5v5 play so they aren't relying on guys like Patrik Nemeth, Dryden Hunt & Julien Gauthier to play major roles down the stretch and in the playoffs.
The players and fanbase deserve the opportunity to bulk up for a playoff run after being patient with the rebuild. They werent prioritizing winning for 4 years, but they still charged just a much for season tickets. And now The Garden is dying for another run, anyone who has been there will attest to it being as energized as it has in years. With Panarin/Fox/Igor/Mika/Kreider, they can hang with the big boys. With some smart deadline additions, they can beat them.
This is the start of a strong 5 year window. Nothing after that is guaranteed once Panarin's contract is up, and this very likely will be their best and only chance to add significantly at the deadline due to the incoming cap crunch. They can hoard picks & prospects in the upcoming years when they dont have deadline space to add, if thats really what we are worried about.
