QB rating

By Tangotiger, 03:52 PM

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?
