Barring a massive locker room divide, I'd be shocked if Tkachuk was dealt.
If Calgary doesn't see this group contending in the manner that they'd like, I can see a retool. It's so difficult with the flat Salary Cap though.
Gio is still great, but nearing the end of the road, and I can see a contender being interested, if they have a need.
There is some dissatisfaction with Monahan, but he's appropriately paid for a 2nd line C, and at times has shown more upside than that. It's hard to replace what he brings, even if he hasn't met expectations. Some comments about him not showing in the playoffs, yet 8 points in 10 games last year...
Of course Bennett's name has been out there, but so far no deals.
