In the case of Wisconsin they've played 3 more Q1 games, and just as @CheifIllini said they've won against higher ranked teams, and had bigger wins.
So far, I'm happy with where we are at in the rankings. We are about 50/50 on one possession games. Had we won @Maryland, vs MSU, and Miami and Mizz games then we'd be top 10 in NET, probably #5 or #6. Win those 4 games and we have a better resume than Duke and Louisville. We could've also lost @Mich, @PSU, @WI and we would probably be around #70 with a resume similar to St John's. Every game matters.
