I would very much like to mess with the data you have to see some things, mainly to see where the cliff that Markstrom fell off was.
I also would be interested to see if any opposing teams score a significant amount more stoppable goals than others, or if it’s just random.
Markstrom is a weird one. I CLEARLY remember (maybe I'm wrong, you can find out when I send you the data) him not having a high percentage of goals I counted stoppable in 20-21 when he had a down year. The first year in Calgary. I had him for a higher percentage last year. I forgot if it was worse than my league average or not. It may have been slightly worse, but not way worse. This year, I think have him right under 30%. My league average for this year appears to be about 27.5% or thereabouts. Last year it was closer to 28.5%. It's seen an uptick in the last few nights, as I think it was around 26,5% just a week ago, my league average.
There are some deviations, like Korpisalo usually doesn't play as poorly on my percentages as his save percentage of GSAx. Jonathan Quick also doesn't, but it's an extremely easy answer as to why. He flops way too much, he plays A LOT of the game on his ass and these are goals that I can't in good conscience nail him for a ''Stoppable goal'' on, even though A LOT of them definitely are stoppable goals, due to way he plays them. That's why my stats are not infallible or to be taken as gospel. There's a lot of plays where a goalie will overcommit or flop or something and lose their net, and I won't nail him on that, but in all actuality, some of these are probably not good goals, due to the goalie's poor reads and guesses. Kevin Lankinen was like that last season. I don't let confirmation bias play a part in these, but if I see a goalie is playing poorly, but don't have him looking that poorly in my stats, I will start to pick apart what I think they're doing wrong, but I will leave it out of my own my stats.
Strangely enough, I do not have John Gibson down for a high percentage in any of these decline years. I kind of do this year, but he's also not my highest percentage in the league. It is kind of early and some goalies don't have an adequate number of games played yet, especially relative to what they'll finish with at year's end.
I think Martin Jones in 18-19 was mediocre or near average on my stats, but not as terrible as his save percentage. I think in the years since it's definitely gotten worse.
Anyway, you're more than welcome to pick apart my stats. I am about to run out, so I'll send them to you via PM if you'd like.
I just wanna caution, you may find them hard to read. Basically all they are is the goalie's name and a number, and that number is the number of goals I counted stoppable on them. If the goalie's name does not appear on my list, but he did play a game that year or even allowed a goal that year, it just means that I didn't count a goal stoppable on him. And I don't have save percentages next to the goalies or their actual goals against, as the league and every other stats site tracks those for me. The number is just the number of goals stoppable I counted on them for that year. So you'd have to go and look up their goals against/save percentages/GSAx and compare, as I never kept track of those.
Let me go through my emails and I think I can find the ones for 18-19 and 19-20 right now. As well as the 18-19 playoffs. I'll send them over to you in a few minutes. And then I'll send the other seasons in a bit after I come back home and eat something, as I have them on my phone, but it's gonna be a little harder to send them, as I'm not sure if I have to screen shot them or copy and paste and I really don't wanna lose them in the process, even though I think I have emailed them to myself also, just in case something like that happens.
