This isn't a super bad deal. I mean, Howson's hands were tied. Nash had a list of teams he wanted to play for and of those, only a couple of them had the assets / cap room to pull it off. The Rangers have always been the obvious choice. Sooner or later Howson had to give in and while yeah, he should have taken that deal at the Trade Deadline, this still isn't a bad deal. Two Top 6 forwards (yes, they had down years last year, but I still think they are Top 6 as I watch the Rangers a lot), one of the best D prospects not playing in the NHL, and another 1st round pick. The Jackets now have three in next year's draft, which is supposed to be very deep. Think 2003 all over again. That should mean either three very good prospects or package one or some or all of them up into legit star players.
Howson's goal all along was two NHL ready forwards, a pick, and a prospect. That's exactly what he got. Of course the two guys he got that are NHL ready aren't stars and are coming off down years. They now boast a very average Top 6, but at least it's a Top 6.
Unfortunately, the Jackets have to look long term. Think "rebuild" yet again. Highly doubtful they can be competitive this coming year, but take those draft picks, hopefully one or both of those goalies they just drafted, Murray, Johnson, Johansen, and in a few years, be very competitive.
I've said this before, I'll say it again: The best thing they could do this next year is finish last again and draft Nathan McKimmon. There's not much else they can do at this point but go for that. And hope the fans stick around, of course...
