Over the next nine years the 16 team Big 12 will host SEC/B1G opponents an average of 3.4 games per season. On average that is less than once every four years per team. Now I'm not saying everyone needs to host one of those teams every other year, but less than once in four years is pretty slim pickings. And fortunately BYU is owned return games from Independence or we'd be down to just one SEC opponent in the next nine years.
