I’d like to hear more about your thoughts on Binnington’s declining performance as the season progressed and dismal performance in the postseason. The trend is concerning. That’s more what I think will dictate how many starts go to each player, not simply fatigue.
I think my main thought is that I don't really agree with the premise. Like almost every non-elite goalie he had ups and downs, but I wouldn't really say it was a "trend" of declining performance. And since he posted a .926 through the first 2 months of the season he was either going to regress to the mean or be the best goalie in the league.
.912 in starts 1-10
.939 in starts 11-20
.896 in starts 21-30
.886 in starts 31-40
.921 in starts 41-50
That stretch between starts 21-30 included the Leafs game where he allowed 4 on 11 before getting yanked and the Avs game where he allowed 7 on 41 shots. 5 of those 10 games were against top 10 offensive teams. It is worth noting that he allowed three or fewer goals in 7 of these 10 starts and allowed two or fewer in 5 of the 10 starts. He got blown up a couple times vs top offensive teams in the league but was otherwise very solid. Excluding the Leafs/Avs games his SV% for the other 8 was .921 in this stretch. That just isn't a period of decline.
The stretch between starts 31-40 included the Avs game where he allowed 4 on 11 before getting yanked. We only played 3 top 10 offenses in this stretch, but we also only played two teams in the bottom 10. Not a hard stretch, but a pretty average one. This is the 10 game stretch that was concerning and he responded by posting a .921 before COVID shut things down.
Let's look at the numbers month-to-month:
.918 in October
.934 in November
.904 in December
.866 in January
.908 in February
.934 in March
.914 if you combine February and the 3 games in March
Again, that just isn't really declining performance as the season goes on. Month to month goalie stats are almost always all over the map and there are just a handful of elite guys who are consistently good. He had an awful January (where I thought he looked tired and was pretty regularly asking why he was top 3 in the league in starts when Allen was playing so well). Other than that he bookended his year with 2 above average stretches of play and another couple stretches of okay play.
This is what average starting-caliber goaltending looks like with a heavy workload. You get average goaltending about half the time and then some stretches of outliers going each way. I don't think there are 10 goalies in the league who would have been more consistent AND ended the year with a higher SV% with the workload he faced. I think a ton of people vastly underestimate his workload. There were only 5 goalies who had a higher expected goals against. 4 of those 5 guys had a negative GSAA. The other guy won the Vezina. There was only won other goalie in the top 10 goalies in expected goals against who had a positive GSAA. He was the Vezina winner in 2018/19. Binner was one of just 7 guys to start 50 games and he was 6th in TOI. My opinion is that we asked waaaay too much of him, but that is probably a different discussion.
As for the playoffs, I don't have enough info to have a strong opinion. It could be that the Canucks scouted him and figured something out in his game. It could be that their counterpunch style was a bad matchup. It could be that he was one of our guys who got COVID and he was just gassed. It could be just a completely random slump. The only thing I'm comfortable saying is that it wasn't a simple
continuation of any downward trend. His play had been trending upwards for the last month+ of the season and then we took 4+ months off.
At the end of the day, we're talking about a 19 start stretch where he posted an .887, compared to the .926 he posted over his other 31 starts. And then an awful playoff bubble where he didn't look remotely comfortable on pretty much every shot he faced. I think this is much more attributable to what happens when an average goalie is asked to handle an elite workload. You are going to have up and down swings.
I have my concerns with Binner, but they aren't any more than they were on the eve of the season opener last year.
