only 3 home non-conference games (and 4 non-conference away games)? With BYU rebuilding this season, every game could be a challenge for BYU this season. Wisconsin is a usual top-25 type team - they played in second round of NCAAs last season. I think that's a decent enough schedule.
BYU has 6 conference home games this season, so still same total number (9) of regular season home games this season as compared to last season.
