Why would you want to replace the scouts? They're largely responsible for selecting what many feel is the NHL's best collection of prospects.
Also don't see Calgary flipping Hamilton only a year after acquiring him.
In terms of the scouts, I believe Maloney had some say in who was hired (for a "build for the future" approach). With the new philosophy coming in, scouts aren't as important (at least for the next two seasons) since most spots will be filled by mid career players or UFAers. If I were a scout hired by Maloney, I'd probably be hunting for a new job (or waiting to see where Maloney ends up). My point is that the scouts and Maloney probably worked together aplenty, so if they thrived in a Maloney regime, they won't in a Tippuppett one.
I could see Calgary making the deal if they can fleece the Coyotes, but he'll probably remain in Calgary. I'd take Trouba (depending on what it would cost us)
