The issue is that despite being a solid scorer, the Blues get badly out chanced with Schenn on the ice to 45 percent of the expected goals in 2021-22 and just 41 percent last season. Both were well below the team average, with most of the problem stemming from Schenn's inability to suppress chances against. That wasn't a huge issue in 2021-22, but the good fortune ended last year as Schenn's defensive numbers worsened. That led to Schenn only being on for 46 percent of the goals.
