Great article by Tierney today in the Athletic contrasting the Blues defensive performance last season and so far this year. Great deep dive into some underlying stats with well explained charts. A few points that stood out:
- Blues are allowing the 3rd least shots against in the league. However, unlike last year they are ‘more dangerous’ scoring chances (with an expected goals per game that is more average despite the low total shot volume). Last year the xG was crazy low. It’s not clear to me why this is different. But it makes me wonder if the weight being placed on shot location to generate the expected goals numbers is somehow misleading. Maybe the straight Corsi has a bit more value than current conventional wisdom.
- Intuitively, if the shot quality is tougher, you can conclude correctly that the goaltending is above average. One way this is expressed is Goals Saved above average per 60 minutes. Binnington is solid at close to 0.2. But Allen so far this season is near the best on the chart at 0.6 per 60. If you lumped Allen’s stats in with all the NHL starters, he’d be 7th best in the league. I realized he’d been playing better, but not that much.
- GMs around the league will be highly aware of this. Despite the narrative around here that it will require adding assets to move Allen, the reality is that he’s turned into a plus value asset. He’s the perfect platoon goalie: a guy who costs less than most starters, on a short term deal, with significant starting (and playoff) experience. I see no reason the Blues move him in season, but they will be able to easily find a match in the off-season.
- Finally, I wondered if the xG discrepancy should concern us more about this team’s post-season outlook. For me, I think they aren’t playing at post-season intensity like they did for the 2nd hard last year. I also think working in Faulk has led to some vulnerabilities that should improve (and have been improving). But it’s pretty crazy that the Blues have turned into a team that is carried by the strength of its goaltending much of the time, earning points that average goaltending would not provide.
