The question is whether or not that is predictive going forward. I believe the yds given up are more predictable than the 1 play here and there that may change the outcome of a possession.In many cases it's points allowed. Take Okie State last year for example. They gave up 446 ypg on defense, yet they led the Big 12 in fewest points allowed. The reason was because they were +22 in TO Margin, and they had a very good red zone defense. In other words they were a bend but not break type of D. So the yards allowed between the 20's really didn't mean that much.
