We always play 20 conference games, so 20 of the 23 power conference games are Big Ten games. We always play Seton Hall, so that only gives us 9 OOC games that we have to worry about scheduling.
Of those 9 OOC games, we had 2 power teams (Miami and St Johns). It was the other 7 that killed our SOS. Maine at 328, Columbia 243, FDU 236, Drexel 226, Boston 224, Fordham 219. Only Eastern Michigan was in the top-200 at 154.
Compare that to Nebraska who played 5 power conf teams OOC (Seton Hall, Creighton, Texas Tech, Clemson, Okla State). Of their remaining OOC games, only 3 schools were below the top-200 (Miss Valley 349, W Illinois, 304, SE Louisiana 281). So they have a stronger SOS.
For next year, if Rutgers isn't expecting to be on the bubble, the SOS doesn't make that much difference. But if we're playing for the bubble (or NIT bid), then we need to upgrade our OOC schedule.
