This year's Rangers are not a tough team. Last year's were kind of tough--not anything extraordinary. It's an element that helps in the playoffs. Last year Ottawa, Washington, New Jersey all had big wingers who could grind all night long. Eventually the attrition wore our team down. Finding players that are big, tough and can play is not always an easy thing. Here--sometimes people just want to find more offense no matter the type of player. Skill is a big part of winning but it's not enough on it's own. Look at what happened to Pittsburgh last year--and they're having problems again this year.
How to put together a team that has enough skill, enough defense, great goaltending, enough size, grit and youth and then there is depth--and then fit it under the cap and be a legit contender at the same time? It's a rubik's cube. Throw in the elements of lucky bounces and no or very few injuries. That's how you win a championship.
Just take away one element and the whole thing falls apart. Holding things together is another thing which is almost an impossibility.
