Realistically, unless Calgary flubs things, he should be.
Seems unlikely we're interested in moving Lekkerimaki or Willander which leaves interesting, but unspectacular pieces.
Our 1st will be middling at best, possibly later, next year's 1st is probably more of the same alongside our 2nd. Podz is interesting but has yet to prove himself, Raty is just potential at this point, so is Bains. Hoglander could be interesting to them, he's shown more at the NHL level but he'd probably be a complimentary piece in any deal.
Calgary can, and should, retain 50% to up their return. If they do that they should be getting at least a 1st from another playoff bound team plus a top prospect if they're taking neutral or negative cap back to facilitate the deal.
Lindholm isn't what he was a couple seasons back alongside Gaudreau and Tkachuk, but with the center market being thin he doesn't necessarily have to be.
If Calgary wants to turn things around sooner than later they're probably better off shipping him East too as opposed to trading him to a direct rival, because odds are if we trade for him we'll probably try to extend him.
