Fun fact about Schenn:
151st out of 153 defensemen with over 50 PK minutes in GA/60 on the PK this year (over 15 GA/60). VAN does get terrible PK goaltending, and the two guys worse than him are also on VAN, but his xGA also suck (131st) while OEL (152nd in GA) is 22nd in xGA and Bear (dead last) is 109th.
Holl, comparatively, is 12th in the league out of 153 defensemen with 5 GA/60 (Morgan Rielly is surprisingly 6th in the league after qualifying with enough minutes as our #5 PK defenseman) and 33rd in xGA/60.
Schenn has had some actual success running shotgun with Hughes, but his underlying numbers suck with him and away from Hughes, he is not even NHL-caliber. So there is a 3rd round pick effectively riding on him being significantly better with TOR than he was in VAN and working well with Rielly, because otherwise, he is effectively a RH version of Jordie Benn... Which puts him 9th or 10th on our healthy depth chart with Holl still on the team.
Throwing a ton of hits doesn't make up for being a terrible defenseman who is worse than 8 other guys on our depth chart.
