1) That statement is not accurate.
I think I've been fairly consistent that its counting stats w/ the advanced metrics to go along with it. If I had to pick one or the other yeah give me the advanced metrics over total yards to tell the fuller story, but both matter. If a WR has a 3.0 Y/RR and plays 30+ passing snaps every game of coures he is going to have monster counting stats to go along with it. I've never argued that a guy like Justin Jefferson shouldn't be considered a top WR, I'm just saying its foolish to rule out 1,000 yard player on lesser snaps. The WR with 1000 yards on 450 routes is way more valuable than the 1000 yard wr who ran 600 routes.
2) Lol so advanced metrics are a good thing when it props up your QB, bad when it's inconvenient and suggests your stud WR was good before the Cowboys acquired him. Just because these stats aren't readily available to the masses doesn't mean they don't offer value. I'm not sure how much the rankings even confirm QBR is a go to stat per the expert rankings you've shared....The top 3 QBR leaders from 2025 are ranked 8th, unranked, and unranked.
