As
@Rielly4 alluded to, that hasn't necessarily yielded results.
Gibson, Bobrovsky, Binnington, Murray, Grubauer...
Outside of Price, Vasilevsky, Hellebuyck, Shestyerkin, Demko, Saros, and Markstrom, I am not sure anyone who is currently making 5+ mill right now should be making 5+ mill, and Price is not worth anywhere close to what he is currently making. Kuemper may join the low end of that list this year, and a few guys who are coming up now or soon like Oettinger, Swayman, and Sorokin will likely justify it too, but there are almost 20 goalies making 5+ mill in the NHL right now and not even half of them are worth their cap hits (and also why Campbell is not worth anything more than like 4.5 x 2 like what Kuemper got a few years ago). You can even toss Fleury, a younger Quick, Crawford, Holtby, Andersen, Varlamov, and Rask into the mix as guys who recently made 5+ mill and were worth it for some stretch of time, and you maybe get to 60% (although I could include some other busts in there which bring that percentage down again).
Meanwhile, we get guys on ELC's like Murray and Binnington and random ass backups like Khudobin going beast mode and leading their teams to Cup Finals or wins.
It is not completely random, but goaltending is by far the most volatile position in hockey. Unless you are confident you have a really good goalie (i.e. consistent top 10), you should not be locking in big money on goalies (and certainly not on older goalies). Even then, there is pretty much a hard cap at 5.5 mill or whereabouts because as soon as you get north of 5.5 mill, you need a guy who is consistently challenging for top 5 in the NHL.
Gibson is making 6.4mill, and he has played closer to a guy who makes somewhere in the 4's the past 3 years. Blame the team, but there have been guys who have played on worse teams and have looked better than him, and they don't make anywhere close to 6.4 mill. There is still some upside in him, but that contract is a major poison pill and not something that I think a lot of teams will find overly attractive without retention.
If Gibson came with over a mill in retention and they took on Mrazek like they did with Bernier, I could maybe see them getting an Andersen return. They aren't getting a Kessel return.
