Eh, this is a little disingenuous. Rinne did not have several years when he was bad, he has at most two that could be considered "bad", and one of those he only played in 24 games.
Luongo's play was never in question, they just had another guy who was cheaper and almost as good. He still was really good.
Same thing with Fleury, who still won two cups as the starter.
And quick's save percentage has been under .915 three times in 11 years, and one of those it was .914.
The best thing about Gibson's contract is that it's going to capture his elite years. With almost every elite goalie playing they are almost all early into huge contracts after they have already delivered 10 years worth of top tier goaltending. Bobrovsky is next.
Rinne has season of .902 (43 of 48 games), .908, and .910 (66 of 82 games) in the last 6 years,. That’s not the kind of performance you want to be spending more than 1-2M on. His career playoff numbers are .911, .907, .929, .909, .906, .930, .904. Those are not elite numbers, and I personally think they are “bad”. YMMV.
Luongo was not getting starter games at the end of his time in Vancouver. That’s got nothing to do with cost. He did do quite well at first in Florida (and is still quite good for his age)
Fleury lost the team far more playoff series than he won them. We don’t have 2 generational players.
Quick’s SV % has also only been above .918 twice in his career.
It’s not disingenuous to point out that there are very few goalies who are legitimately elite for 8 years in their play and not just their reputations.
I’m not saying Gibson WILL be an issue. I’m saying it’s pretty easy to find reasons why long term goalie contracts are a bad idea, especially with a goalie with a groin made of glass. Clearly, I’m hoping he proves me wrong.
