"Scoring Chances" are just binning what should be a continuous variable. Not a fan of this stat. xGF% is better to understand the quality of chances the Jets are taking and giving up. According to mannyelk's xGoals model the Jets have an xGF% of 47.79% good for 20th in the league while rocking a 45.9 CF% good for 25th in the league.
Moreover atleast this season the Jets' relatively better xGF% to their CF% is coming mostly from restricting xGA. The Jets xGF/60 is terrible and 6th worst in the league around the same place as their Corsi, which again indicates a team that stays hemmed in their zone.
So yes is some truth to Jets restricting the quality of shots against but that only goes so far. Last season the following teams overperformed their xGF% relative to their CF% by more than 1%:
Wild clearly seem like an oulier of sorts, Bourdreau is doing some vodooo there. The Jets so far this season are around where they were last season. At best I think we can expect them to be around where the Pittsburg Penguins were last season. That still means only a 2.3% bump above their CF% even in the likely best case scenario. Even then the current 46% Corsi means that wins are unsustainable in the long run unless something changes. If the Jets hope to be a contender they need to be able to come close to atleast breaking even in the shot battle. The fact that the Jets are not playing enough in the offensive zone is unmistakable and that is something that is on the coach to address.
