To be fair, he was 9-2 with a 2.18 GAA and .932 SV% in his last 11 games. He was on absolute fire to end the season/playoffs.
He had bad slump after he got Covid. He was really good to start year too. It’s almost like he’s actually good goalie.
His ranks among goalies to play at least 15 games (900 minutes) over the full season
90.1 save percentage (31st)
GAA 3.13 (48th)
He had a 18-4-4 record.
If you wanna look at more advanced metrics
GSAx -10.01 (41st)
GSAA -7.45 (42nd)
He was placed on covid protocol on December 2nd, at the time he was 8-5-3 with a 91.2 and 2.80, his GSAA was 30th (-2.92) and GSAx 22nd (0.86). He was on par with about the league average goalie.
After December 15, he was activated. His numbers were 89.2, 3.41 good for 10-9-1 with a GSAA of -8.46 (60th in NHL) and GSAx -10.87 (59th). So between December 15th and his last eleven starts must've been unfathomably bad.
I like Binnington, but in 2019-2020 and 2021 he was basically on par with the league average goalie by most advanced models and in 2021-2022 he was one of the worst starting goalies in the league, if you even consider him the Blues #1 goalie last season. If you don't, then he was a pretty mediocre backup goalie.
Compare that to Husso last season:
25-7-6
91.9 (8th)
2.56 (14th)
GSAA 14.11 (10th)
GSAx 14.18 (7th)
Is Husso truly a top ten NHL goalie? Probably not. But, he was critical to the success of the team last year. Without him, it's very easy seeing the Blues potentially miss the playoffs.
I do think Binnington is better this coming season, but his prior two seasons to 2021-2022 suggest that he's basically right on par with a league average goalie. 6M is a lot to pay for a league average goalie.
