I am not sure, but my reaction to pretty much all of them:
Kylington in particular should be pretty much untouchable unless a cost-controlled NHL star player or Boeser-type RW prospect is in the return. All his perceived weaknesses turned out to be overblown and easily fixed and he had a fine draft+1 year in the AHL for us, and with his incredible skating has a lot of margin for error anyways. Other knowledgeable Flames fans like Caged Great have noted that he is now as a 19YO where Brodie was as a ~22YO. Why we would let him go for anything short of a glaring long term team need is baffling.
Fantastic pick, kind of reminds me of Nylander in that respect.
