Consistently? Never. I don't see any reason that's going to change anytime soon. I'm not sure what you're getting at. My only point was people keep using stats from games against easy opponents to make their arguments. I don't think that's a good measurement. There's a lot of D1 QBs who will have solid games if they are playing against terrible defenses.
If you look at the success of teams in ISU football since the '90's you will see that ISU can attribute the success they did have to relatively easy schedules. Even look at some of your elite programs. Look at how the SEC protects their top teams from beating up on each other too much, allowing them to play an easier schedule.
To be honest, we need to win the games we are supposed to and then win some of the games that are tossups. Throw in a few upsets and we are in for a pretty good season for ISU. Contend for the National Championship or even Conference Championship? Doubt it. The moon and stars would have to line up for that to happen as well as a severe cold snap in Hell.
