Games by school:
Kansas - 4 (2 home)
Oklahoma State - 4 (2 home)
Iowa State - 2 (1 home)
Oklahoma - 2 (1 home)
Baylor - 2 (1 home)
Kansas State - 2 (1 home)
Texas Tech, TCU, West Virginia, and Texas all got zero.
Seems about right... Basically a round robin to showcase of the best 5 teams of the Big 12 nationally. The star power of KU and OSU draw eyes thus there programs get the extra games.
