It’s largely useless. Over time, as a volume stat, it can show more value, but in general, meh.While I whole heartedly agree with your logic there...it doesn't work in all cases. 99 billion served at McDonald's certainly doesn't mean its good food
But qb wins isn't a useless stat. Its similar to pitcher wins in baseball. Yes Aaron Rodgers went 6 and 10 in his first year as a starter. And qb wins didnt mean sht cuz you could see that the qb did enough to win but the rest of the team didnt. Over a larger sample size, what happened? Rodgers qb win/loss record improved dramatically which coincided with him becoming one of the greatest to ever play the game
Matthew Stafford, Trent Dilfer, Eli Manning, Brock Purdy, Justin Herbert could all be examples of how QB wins can understate and overrate a QB.
The Eagles won more than the Chargers. Is any logical person taking Jalen Hurts over Herbert? I sure wouldn’t. Stafford was viewed as a loser before he went to the Rams. He was the same QB there as he was in Detroit but with a better coach and talent around him, but now people view him as an elite QB who can win games. He was always that guy, just stuck on a crap team. Even Jared Goff! Couldn’t do crap under Fisher, solid with McVay, been good with Detroit, but is anybody taking him over Herbert? I doubt it.
