I think these are all fair questions. But I again feel like these same questions can be posited for a lot of other teams or in similar fashions.
For example, with PIT, will Malkin’s body hold up? The main duo are getting older. Letang as well. How will Jarry respond as being the confirmed #1 with no Murray as a fall back plan? There defense is not all that impressive. There offensive depth on the bottom lines is serviceable but could absolutely be a burden.
Boston. Lost Krug right off the bat. Chara likely returns, and while his leadership is great, he is going to be yet another year older/slower. He likely provides enough to be worth brining back, but a shell of his former self. Bergeron/Krejci can they continue to produce enough to propel this team to the top? Pastrnak will be great. Marchand too. Their center depth is more stable than ours, but what about their forwards beyond them? Yea we seemed to like guys like Studnicka and Frederic in one way or another, but they are just as much questions marks as our young kids, if not even more.
Not gona go through every team, but you get the point.
I am just way more optimistic about your question marks for the Rangers being answered in our favor compared to the question marks of other teams. And thats especially because of the age of the guys we have — as we know they are more likely to trend upward, hitting their ceiling and room to grow, than some of the aging teams such as Boston, Pittsburgh, and Washington finding the fountain of youth and continuing their upward charge. Their window is closing. Their time is almost up. Yes, of course generational talents like Crosby and Ovechkin will continue to perform, Malkin, as well, but father time does not discriminate. Washington will be good again imo. I am not as convinced on Pittsburgh. Boston very well may struggle.
