nope

No, not even close. They aren't willing to retain on Markstrom, and if they were supposedly they could have gotten Holtz for him (see NHLfan10506's ACGM for details). That deal is probably gone now but the entire package you put together might get Markstrom alone without retention. Jarnkrok and Timmins have little to no trade value. Andersson would return something like Chyhcrun at the least, a high 1st (or two 1sts) and more. Something like the 2024 1st + Easton Cowan + Liljegren (maybe Timmins instead if the Flames are super high on Cowan) is probably the best Toronto could/would offer for Andersson that would be considered.

They were actually willingly to retain on Markstrom but this trade is not enough for either of them. (The value may be close in a vacuum for Markstrom but Flames don't want either of Timmins or Jarnkrok)

that’s an insanely weak offer lmao

Not a snowball's chance in hell. Even if you took Andersson out Calgary would still decline.

Maybe if you replace Jarnkrok and Timmins with Knies, Cowan, and Minten.

It'd be less of an overpay if you added Matthews than this is an underpay for the Flames lmao
