Now that I've had the night to sleep on it, although I find the reported TB deal very tempting from a pure value point of view, at the end of the day I don't do it (unless the prospect coming back from TB is one of their top 5-7, which I highly doubt it would be).
In the end, it's still a "win now" move - that I frankly don't think results in the Rangers winning now.
Whereas it does detract from the Rangers' chances of winning over the long haul. Yes, Hagelin tops out as a 3rd liner, but he's an excellent 3rd liner, who can slot up and down the lineup as needed, with many great years of hockey ahead of him; Kristo is a good offensive prospect and, while we are running a high risk of losing him as a Group 6 UFA next summer, he could still be traded for other pieces to a team like Buffalo or Florida that can get him the requisite number of games played in order to retain his rights; and a second round pick has real value, especially to a team like the Rangers that have dealt away 1/4 of their picks over the last four years, including both their 1st and 2nd last year.
I have no problem dealing any one of those assets, but until we acquire the core pieces we're missing they should only be used in order to get those pieces.
Furthermore, I'm terrified of what such a deal would signal regarding the organization's overall strategy. If we deal for MSL, does it become all about his "window"? Are we going to pony up for Kesler? Re-sign Callahan? Keep Drury? I really don't like the dominoes I see lined up behind this one...
So, while I believe the proposed transaction as it was reported would be excellent value for the Rangers, I still don't think it's the right move. (Again, unless you're getting one of their better kids along with MSL.)
