This is buffalo... but on topic of the trade proposal reams usually make trades based on their current phase contender, rebuilding, retooling etc... so if Calgary trades Andersson it would signal a rebuild, Andersson+Coleman for unprotected 24 1st, joki, Krebs, Rosen and 25 2nd
Cozens I get is an ideal target but is signed already for 7 mil not bad still expensive while the flames have to ride out the huby contract until they can buyout. Krebs is currently a bottom 6c heart and soul guy who is still young but has a more to give and a more clear path to a top six position with less logjam either way still a useful player. Rosen has top 6 potential speed and skill I think he settles into mid 6 40 point wing good on both sides of the puck. Joker to fill in at rhd although not as good as Andersson he has reverted back to more decent play this year solid top 4 and younger could fit in well with your timeline and the 1st this year which currently is a top ten pick and it's unprotected so you have another shot at celebrini to me that's a fair hockey trade and just because buffalo has better prospects doesn't diminish the value of our other ones, for example we didn't get kyrou or Thomas from st.louis when they were higher on the depth chart even though Thompson was a good prospect he was a gamble and it turned out nice for both teams.
