Or this

Blues still cannot trade Parayko.

Cgy declines. If they commit to moving assets it won't be for a bunch of stuff, they need some mix of 1st/2nd round picks/prospects coming back in any of the trades they make.
This is especially true for any retention they give, that alone would cost something like a mid round pick

Calgary would take this trade easy

Brodie =< Tanev not a huge difference

Then you get 2 more players and 2 picks?

Still a no from Stl
Guys we’ve been over this, give us some good prices back that work and it might happen. Until then can I interest you in a Krug or Leddy or even a nice Faulk

I'll let the Flames fans weigh in but from what I've heard this isn't what they want for Tanev.
What value do those players have? Holmberg is a bottom 6 player thus far and Abruzzese is a career AHLer with 2 NHL games at 24 years old. Those aren't assets that intrigue a team looking for futures and picks. A third is what you're paying in retention so its Brodie and a 3rd for Tanev, with Brodie being a UFA and 33 years old?
