I don't think this is a hot take, but I think there's a very good chance Ryan Murray is traded at the deadline.
He's rarely played - both in terms of games (23) and ice time (14:07) - and has been below average (sometimes brutal) most of the season. I thought his contract ($2M) was going to be a bargain, but it's one of the worst on the team in retrospect; Murray would definitely be in the press box most nights if Bowen Byram was healthy.
Even if there was a massive wave of defensive injuries in the playoffs, I think Bednar would spread the minutes (and give sizable roles to Justin Barron and Jacob MacDonald) before we'd ever see Murray playing 20+ minutes a night. In other words, I don't really see him as an insurance option; just as a third pairing defenseman who's already struggling with sheltered minutes.
We'll see what happens, but if Colorado trades for a defenseman, dollars to donuts Murray is going the other way as a cap casualty.
