That’s if you’re a big believer in the team’s goalie of the future, Igor Shesterkin. He certainly looked the part to start his career with a .929 save percentage over his first 12 games, saving six goals above expected. That’s half a goal per game, which would be an absolutely ludicrous full-season mark.
A 12-game sample is hardly enough to go on though. Shesterkin has a lot of pedigree, frequently being called the best goalie outside the NHL before his arrival, but this is a position with a lot of variance where it’s better to be safe than sorry. Before the season started I made some big changes to the goaltending portion of the model and one of those changes really impacted small sample goalies like Shesterkin. Essentially, I separated goalies into three buckets based on their previous samples, and when regressing to the mean I only used the averages from the bucket the goalie belonged to. For Shesterkin, that was any goalie with a low volume of shots, basically regressing him towards replacement level rather than average. That he still grades out as a legitimate starter despite that is very impressive, but that still may be lower than many were expecting.
It’s a necessary evil though as Shesterkin is going to have to take more time to prove his worth. Before the switch, the model projected Shesterkin as an elite-level goalie next season worth over two wins. That was enough to put the team at fifth in the East division. While I don’t doubt Shesterkin has an elite ceiling, 12 games into his career is just way too early to make that call.
As good as he has looked, there is a non-zero chance he doesn’t fully live up to expectations.
