I think it's something the Avs could be interested in. Manson is way overrated by fans. Bednar doesn't even think that highly of Manson. He was their 5th most-used defenseman during their Cup run (even after Girard got hurt). And this year against Seattle, Bednar very, very heavily relied on their Makar/Toews/Byram/Girard top-four and used Manson sparingly on the 3rd pair.
His efficacy will only decrease as he gets older and incurs more injuries. The Avs need to improve their forward depth. It's an interesting swap.
It's an interesting observation...how little Bednar seems to want to deploy Manson. I think he was acquired and signed because he fills a very clear and obvious role need in the Avs blueline. They've got lots of smaller puck movers...what they needed, was a big bruiser to fill things out. But when the rubber hits the road...it certainly is interesting that Bednar clearly prefers others.
I think EJs future probably plays into this. Not sure what's happening with him, and that takes us back to the original acquisition of Manson when EJ was unavailable.
If the Avs were actually willing to swap Manson for Garland, i'd take that an run as a Canucks fan. Heck, i'd do Boeser for Manson easy. He's not as consistent and reliable as you'd like...but he's exactly the sort of partner we've been looking for with Hughes for years, since Tanev left. Goes about things in a very different way, but i think it could be a pretty successful pairing if Manson embraces that role.
I just really don't get the impression that the Avs actually want to move on from him. Even if Bednar doesn't use him as much as he could, or maybe should. And even with Manson's durability issues.
