Of the current CFP Top 25, this is the number of true road games each team plays:

6-BYU, Kansas State, Colorado, Louisville, Miami, Boise State, Tulane
5-Alabama, Texas, Missouri, Ole Miss, South Carolina, Oregon, Penn State, SMU, Washington State
4-Ohio State, Indiana, Texas A&M, Tennessee, Georgia, LSU, Clemson, Army
3-Notre Dame

The media talks about strength of schedule. They generally don't talk about where those games are played.
