Right now there are many more problems than goaltending, but goaltending played a huge role in taking us out of contention by about December. It was more Cory than Keith at that point, as Cory was downright unplayable and Keith was the only serviceable goalie until Blackwood got called up. But before Hall got injured we were around 15th in goals per game. That's probably down quite a bit now. We may finish in the bottom 5 or lower in scoring when all is said and done.
Jason Labarbera barely played an era before Kinkaid. He's 9 years older and his NHL debut was 9 years prior. Well, he did play one game in relief in 00-01 where he faced 2 shots and stopped both in 10 minutes of play. He's 9 years older (9.5 to get technical) and made his full time debut in the league 9 years before Kinkaid. Maybe Johnson is the best comparable. 3 years older than Kinkaid, debuted 4 years before Kinkaid. He actually didn't play more than 4 games in a year until the season before Kinkaid's full time debut and first NHL start. The biggest difference to me between Kinkaid and Montoya/Johnson/LaBarbera is that they all bounced around and were journeymen, whereas Kinkaid will likely have only played with one NHL team before by his 30th birthday, but they're very similar.
And how do you figure there are more LaBarbera's in the league than when he was playing? There's always been loads of guys like that. Looking from roster to roster, the LaBarbera goalies to me are Domingue, Brossoit, Dell, Korpisalo, McElhinney Stalock (at best). Allen, Neuvirth, Markstrom, Kuemper. Johnson, Nilsson and Kinkaid. So that's 13 right there. I guess Greiss, Khudobin and Reimer are close enough, but maybe slightly better, as they have better seasons more often than most of those guys do. Other guys that I didn't name are either too new to really properly grade yet and are still fairly young (Rittich, Sparks, Copley, DeSmith, Ullmark, Binnington, Hart, Georgiev, Koskinen, Delia, Campbell). Malcolm Subban is kind of still new and not enough games into his career yet, but he's probably edging closer toward the career backup only spot. Then there are guys that were once starting goalies, that have now regressed to backup status (Smith, Niemi, Halak, Elliott, Talbot). Saros is one guy that seems like he has a bit of a ceiling and could take over for Rinne as the starter in the next couple years.
So you're right that there are a lot of them, but I think there always have been. Terreri was like that when he was with us at the end, only he was really bad by that point. He was a decent 1b over a several year span, I think he was better than Kinkaid. Corey Schwab was also another guy like that, but he was on the very lower spectrum of it all. He was actually a very bad goalie, outside of his random 6 or 7 games with the Devils between 02-03 and 03-04. He was not as good as Kinkaid. And they played so long ago that you definitely can't compare because of the era's.
