Calgary would take that (even though we don't really need wingers)

Coyle primarily plays center, so when looking at i figured he may slot in at 3C for the flames, he could also play RW in a pinch but his strength is at center. it could be a fresh start for Monaha and Coyle could be a stable piece through the middle for the flames for a few more years.

No they wouldn't. Coyle has 4 years of term left Monahan has 1. That reason alone should be enough to decline

Coyle won't waive his clause. Again, the return is not enough for both Smith and Reilly.

He's only got an 8 team not trade list. i suppose calgary could be on it but i suspect there's 8 other teams he'd prefer not to go to.

Still, it's a win long-term but you get a worse player at a higher cap hit in a season they need cap space.
