In recent history, yes.
But, I'll go one more, and say he's been the most overrated goalie of the decade. I've never understood how he's been considered among the elite. A very good regular season NHL goalie? Sure. An elite, Vezina worthy goalie, absolutely not. Although he'll win it because the awards these days are a crap show, "who do we feel bad for this year" or "who's turn is it" PC love fest.
The problem is, Rinne is a good dude and very likable, so he's easy to cheer for. But, if we're being honest, he is very unlutch and overrated.
I would say the most unclutch since Hextall 2.0, and I'm a Flyers fan. After Hextall returned post-Lindros trade, he absolutely let in brutal goals at the worst possible times - any Flyers fan can attest to this.
IMO, in order to be "unclutch" you have to be considered a very good goalie and expected to perform better when it matters. A crappy goalie is a crappy goalie. But "unclutch" means you're good-to-great but just come up small when it matters. Hextall, Rinne immediately come to mind.
