It is still very early in the college football season, but we are at the point at which every team has played at least two games against FBS opponents, and a significant portion of the year's non-conference games are already in the books. To date, 150 of the 194 games played between FBS opponents (77.3 percent) have been non-conference matchups. Only 48 of the 518 remaining regular season FBS games (9.3 percent) are non-conference matchups, and most of those remaining non-conference games involve only four teams: independents Army, BYU, Massachusetts, and Notre Dame.
There is more connectivity in game results between teams in different conferences right now than between those within the same conference.
