Detmer's 175 season would be closer to 160 now.

That being said with offenses built to not turn the ball over today there are some advantages as well in terms of a QB rating. Always good and bad and reading numbers with context.

I think another aspect is that this year's receiver group is elite in my opinion. TEs are probably below average and running game and OL is solid. All of it contributes to what a QB is.
