Have you watched IU play? IU is pretty good. Really well coached. Margin of victory is highest or among highest in the country. The OSU game was 7-7 with a couple minutes left in the 1H then IU gifted OSU 2 TDs on special teams gaffes on both sides of halftime that turned the game (plus OSU scored a late style points TD after an onside kick).
The takeaway here is that we effectively start the season 1.5 games back from most every SEC and B1G team. And that SEC and B1G are going to get the 4 teams they want every year barring some absurdity. And perhaps that we have nothing to gain scheduling strong OOC games because they apparently can only hurt us.
