It wasn't a "let's trade Georgiev so we can keep Hank one more year" thing for me, and I don't think it was for most. For me, this is what we had:
1. Two goalies, one of whom needed to be moved
2. One goalie (Georgiev) who actually had some value
3. One goalie (also Georgiev) who we'll likely be moving on from in the next couple of years anyway
4. One goalie (Lundqvist) who likely required a buyout to get rid of, adding dead money
So given this, it seemed logical to me to keep Lundqvist, not for sentimental reasons but because it was practical. Georgiev won't want to stay here as a backup forever, especially if he plays well, so it's not like we'd be moving an integral part of the team over the next 5-10 years. And when Staal was traded and we freed up all that cap space, it seemed like the need to get rid of Lundqvist for cap purposes was essentially eliminated.
So, IDK. I'm sure there's more to it than what I've captured here, but that was my thinking, and I think many others shared the thought process.
