at 20 games, you are only playing a third of the league twice. Basically 5 teams you only play on the road, 5 teams you only play at home, and 5 teams you play both at home and on the road. At least I'm assuming that's the model they would use.
The question I have is whether the teams you play twice will rotate each year, or if it will be more regionally based (so BYU plays Utah, Arizona, Arizona St., and Colorado twice almost every year).
