I do believe we're at an era where there isn't a ''Top-20'' or possibly not even a ''Top-10'' ranking of goalies. There's probably less than ten goalies that are elite, then about 15-20 or so starters that are average and interchangeable, then there are probably a half a dozen starters that belong in the bottom of the barrel.
I'd say the top ones (in no order) are Bobrovsky, Price (unless his poor play last year continues this year), Holtby, Crawford, Fleury (has been one of the best starters since 2014, even with a mediocre 16-17), Gibson. I think Quick probably deserves a mention. Some of his years haven't been amazing (last year was), but he hasn't had any bad years since the lockout shortened season. Outside of Crawford, there really isn't any other goalie in the league that can say that, at least not out of guys who were already in the league by that season. I think Luongo probably still deserves a mention in this group, at least as of right now. Lundqvist's last two seasons (last year he was fine, kind of mediocre the year before) might move him out of that group for me. He's borderline.
Then you have the bottom of the barrel starters, which are pretty easy for me. Jimmy Howard (one good, random, injury shortened year since 2013), Brian Elliott (has always sucked sans Hitchcock), Carter Hutton (I don't buy him as a stater, despite two consecutive strong backup years), Jacob Markstrom (he's not a starter on an average team), Mrazek/Darling (both suck), Craig Anderson (37 and was putrid last year. The end is near) Cory Schneider (he's shot, two straight garbage seasons, coming off hip surgery, doesn't deserve the benefit of the doubt anymore). Jake Allen deserves an honorable mention in this group. I feel like Mike Smith and Martin Jones might also be closer to this group than anything, but both are still pretty average.
Everyone else (starters) belongs in a group where they're interchangeable and have little to no difference. And that includes Pekka Rinne for me, who's had two consecutive good seasons, but they're his first consecutive good seasons since before the last lockout. And that also includes Tukka Rask, who hasn't had anything better than a solid season in 3 years and has been pretty average ever since. even though people still talk him up as elite.
