Agreed - however I don't think Bowman sees Seabrook as the guy to move.
I see no reason why they wouldn't be able to move Sharp, even if they have to give him up for less than a first rounder. I would be surprised if Dale Tallon isn't interested there.
For the Hawks, I see their roster breaking down as follows:
Forwards ($40m almost exactly): Kane, Toews, Hossa, Anisimov, Kruger (~$2.7m estimated), Shaw, Tikhonov, Daňo, Teravainen, Panarin, Morin, Desjardin (~$1.2m estimated) | Bickell/Sharp/Versteeg traded
Defense ($18.3m): Keith, Seabrook, Hjalmarsson, Rundblad, van Riemsdyk, Gustafsson
Goaltenders ($6.6m): Crawford, Darling
That's only $65m total with the $71.4m cap - of course they'll potentially need to retain some salary on the three forwards they move, but I'd say they value Kruger above any of them, and would be willing to retain a couple million to keep that core together. Also gives them the chance to upgrade the blue line via trade (Schenn?)
