It could also be clearing a little room for a move as well ( a cap hit of 1.3 (if that's right), plus sending back a .5 mil guy to the AHL; since Campbell isn't on ltir I think he is still counting against the cap -so maybe they are looking to upgrade).
I doubt you'll see Scott sent to the AHL unless they are just giving up on the guy entirely (as with his limited skill set you would probably assume if he has to go through waivers he'd be picked up -and therefore just gone). . . he, apparently, only has one skill -and since there are no majors logged in his PIM stats -he hasn't used it - I suppose until that happens - his skill is what his "potential specialty" is.
There aren't very many 19 year old defensemen that play in the NHL - in fact guys like Seabrook and Keith are sort of "freaks" when it comes to that sort of thing.
I had thought about if this could be setting up a trade. But in looking at our player's salaries, I just don't see what they can do. Sharp and Hossa have been our two best players so far this year, so they aren't going anywhere. Kane and Toews are obviously untouchable. After those 4, our only high paid forward is Bolland with a cap hit of 3.375 mil.
On defense, obviously Keith and Seabs are untouchable. Hammer can't be traded until it's been a year since the offer-sheet match. Campbell can't be traded while injured, having the strict limited NTC and his atrocious contract.
All I can come up with is Troy Brouwer. The Hawks probably wouldn't lose much in trading him. The problem is he only has a cap hit of 1.025 mil, so combining Leddy and Brouwer only gets you to around 2.3 mil, and that's with one less player on the roster.
