You're comparing numbers across two very distinct eras. The average team scored and gave up 40 more goals last season than they did in 2014-15, and most of that is in save percentage.
Here's hockey-reference's era-adjusted career numbers, where 100 is average and being lower is better - Hasek is at 79, Gillies is at 120
M.A. Fluery - 97
Vitek Vanecek - 97
Now Vanecek didn't have to play in the NHL so young and so M.A. Fleury's career probably looks more like a 95 without those first two seasons, but yeah, I don't see that huge of a difference between the two.
Well first I'd have to question hockey reference's era adjusted model.
Secondly, in addition to his early seasons, you are also including late career years for MAF.
Just looking at seasons they both played. Both guys played in 30 something games in 2020-21. MAF posted a .928 save%. Vitek a .908.
Vitek over the last 3 seasons, amongst goalies who have played 3000 minutes, Vitek is tied with 4 other guys for 23rd out of 58 goalies in save %. Wedgewood being amongst that group.
MAF from 15-16 through 17-18 he was 8th.
This year, minimum 1000 minutes, Vitek was 19th in save%. MAF was 4th in 20-21. 6th in 17-18. 11th in 15-16. 13th in13-14.
MAF, is not an all timer, but his career is clearly better then Vitek's career thus far.
He got Hart votes in 2010-11 and 2014-15 with Pittsburgh. He’s had Vezina votes in 5 separate seasons in his career. He was a first overall pick. Vanecek isn’t even close to Fleury.
Take the first overall pick out, because some high picks bust.
But he was getting votes because he had some very good seasons. Vitek has one decent season under his belt. And 2 less then decent.
