1. Rest. Both teams played in their conference championship games today. BYU's most recent game was Friday. VCU played three straight and Wisconsin two straight.
2. Location. For a couple of reasons. First is the proximity to Utah compared to Virginia and Wisconsin mixed with how well BYU travels anyway. Should be a lot of blue in the stands.
3. Elevation. Richmond is basically at sea level and Madison Wisconsin is just under 900' above sea level. Huge advantage to play these team in the Mile High city.
