QB rating
When I was a kid, I used to do QB ratings for CFL players. I did something like Yards minus 5*incompletes minus sacks minus 50*interceptions, all divided by pass attempts plus sacks. I didn’t really have anything to back me up. I just sort of reasoned that getting an incomplete pass (losing a down) would be as costly as the difference between gaining 15 and 10 yards. And ths was 25 years ago, so I would have hoped that we can be clearer on the answer. The Wages of Wins tries. In their case, they do minus 3*plays, rather than minus 5*incompletes. I’m not sure I agree that you look at plays (PA in baseball talk) and not incompletes (outs in baseball talk). Also, for whatever reason, they round “35*interceptions” down to “30*interceptions”. What’s wrong with leaving it at 35?
