I just don't think Vancouver would only take Stepan and a B-prospect, you'd have to give up at least a 1st with him, and that's fair as long as Kesler's deemed healthy. I'm not really big on giving up Miller either unless we were getting into E.Kane territory. A late 1st and maybe a Fast I'd think about if Van. sent back a 2nd or something.
I would offer Stepan, middle/solid prospect, solid pick FOR Kesler (2nd or 3rd rounder). That is fair IMO. Maybe someone gives them more, so be it I guess.
