I don't think he's played particularly well. He's been ok. On a team full of play drivers he's the passenger. But, he's a passenger that can contribute in other ways, and has for the most part done so.
But, yes. His shooting percentage is clearly short term bad luck. Using those 6 charts as a comprehensive assessment of his play was superficial, lacks context, and has outright bad conclusions.
He's last in production and goal differential because 3 pucks didnt go in that normally would have (his iXG agrees). Full stop.
His xGF differential isnt near as bad as you're making it seem. Breakeven isnt awful. It's .07 per 60 in the red. Based on 10 minutes a night, we're talking about an extra 5v5 goal lost every ~15 games -IF these numbers hold.
I just find the fly by superficiality hilarious coming from you. Maybe Ritchie's not important enough to give serious thought. But its weird that someone who agrees with the concept I'm talking about, and has argued at length for its application in the past, is doubling down rather than saying "hey I missed that, maybe he(Ritchie) hasn't been as bad as I portrayed." I find it frustrating when a numbers guy uses numbers badly. It gives using numbers a bad name.
