There is nothing wrong with keeping a potential top pairing d-man instead of a more established under 25 forward(cough sergachev).
Flip side there is also nothing wrong if TBL fan realizes they can't keep Kylington in ED draft and TBL fan says pass they will keep Cirelli.
Oh I 100% agree with this, I don't think Tampa would want Kylington, he's not a fit there. The original offer included Dube and Pelletier who are the Flames 2 best forward prospects (if you still count Dube as a prospect) and they aren't exactly bad players to have in your arsenal. Pelletier is probably going to make the NHL and be a decent middle 6 guy and Dube has been really good in this playoffs so far. If he was traded to Tampa I could definitely see him pushing for a 2nd line spot.
These are my 2 favourite teams so I can see both sides of the argument pretty well. I personally really want Tampa to keep Cirelli and hope they can move some of the "less desirable" contracts out instead. On the other hand I also think teams that want to OS him 6M+ are dumb, he is a great shutdown center but I think his offensive production comes from the people he plays with more than from him
