Let's look at the East standings, shall we?
1) Boston
Already made their moves for Orlov. They have no 1st, no capspace, and have very few prospects or draft picks of value left in their system. Probably done.
2) Canes
Tons of cap space, tons of prospects, tons of draft picks. We'll do something.
3) Devils
Tons of prospects and draft picks. No cap space. For next year they have oodles of cap space but they also have to re-sign at least 2D and 8F and 1G. Jesper Bratt will cost probably $9M of their $36.6M left. They'll probably do something at the deadline.
4) Toronto
A few decent prospects, but they already blew their draft pick wad for the next few years. No cap space. They can add a depth D but that's it, and even that will be hard as they don't have an unencumbered 2nd or 3rd until 2025.
5) Tampa
They haven't made a move, but they also have no cap space, no 1sts this year or next, and no good prospects. With their raises to guys next year, they're pretty locked in to their roster. I can't see them adding anything other than depth.
6) Rangers
I can't imagine they'll get Kane without dealing their other 1st. Kane and Tank on that offense would make it an absolutely deadly top 9. Yikes. They're in a cap hell of their own creation with some younger players, most notably Miller, needing new deals next year, so I can't see them going for term. To me it seems from the outside that them getting Trocheck prevents them from doing much else down the road.
The wild card group
Islanders
Already made their move with Horvat.
Detroit
Can't see them going all in with where they are in the re-build. Probably a "stay pat" team. Same for Buffalo.
The others are too questionable I think to make it to the dance that I don't think they'll do much either.
