I think the most interesting thing about the trade is the incredibly wide set of possible outcomes. Given the number of players involved and their relatively young ages (except Stafford, of course), there is the possibility for either team to hit a home run here.
Buffalo only has Kane for three seasons before he is UFA. Even if he reaches 40 goals playing with an elite centerman drafted this year, will Buffalo really be a Cup contender in three years? What happens to him then? Does he make a full recovery from his surgery (although initial reports are good)? Does he struggle to mesh with a team that will likely be bad next year as well? Will Buffalo end up trading him in his UFA year? What return might he bring?
Bogosian has four years left and it seems that he may be the most predictable piece. Even then, it is four seasons where he will be asked to play 1st pair minutes on a body that has not typically survived his style of play for 82 games.
Kasdorf has the longest potential career of any of them and, as I'm told, "goalies are voodoo". If he becomes a 10-year starter for Buffalo, that has to be a big win. On the other hand, he could just as easily never make it out of the AHL.
On our side, leaving Stafford out of it, Myers remains young with four years left on his (very appealing) contract. If he blossoms as a top 2nd pair offensive defenseman, approaching Buff's offensive levels, that would clearly be an upgrade on Bogo. Alternatively, he may wilt under the physical pressure of the Western conference and be relegated to 3rd pair duty (yes, I understand that being the 3rd RHD on the Jets rights now means you may still be pretty good).
The three prospects/picks are unknowns, like Kasdorf. If the Jets turn two of them into long time top-9/top-4 players for the team, that would be an outstanding return, and likely tip the trade in their favour. They could also all be busts...or they could hit on all three.
In short, this trade has the widest set of possible answers in ten years time to the question, "who won that WPG-BUF trade back in 2015?" I'll be fascinated to see how it turns out.
