I wouldn't be surprised if whoever gets him looks like a genius in a year or so. Buffalo tends to give good players away, and you can run him all next year too, before his buyout cost goes up from a measly 1.18. So basically a season and a half test run of a big RHC that has scored 30 goals, with minimal downside if you can't turf him if he doesn't work out.
Unfortunately, I don't think we have the pieces to make it work. Buffalo probably doesn't want picks/Prospects at this point. Also I don't think this management group is keen on a reclamation project that would tie up that much cap space.
I would be a fan of the move, depending on cost.
