Before I begin the annual rant analysis, here are the changes to the composition, courtesy of Dr. Wolfe's NCAA and NAIA Divisional and Conference Affiliations.
The 2018 schedules are not quite as well-connected as 2017's. Only 25 of the 130 teams in Division 1A play 12 games against 1A opponents, and three of those also have an FCS opponent thanks to road trips to Hawai'i. 58 teams have an average pathlength to all other teams greater than 2.5, which is the average distance between all 8,385 team-pairs. Only 43.8 per cent of the pairs are connected by no worse than an opponent's opponent relationship. All of those numbers are a little worse than 2017.
This charts the 1A team-pairs with a scheduled game in 2018. The teams and conferences are left-to-right and top-to-bottom in the same order as in Division and Conference Affiliations list. There are two points for each game, so the graph is symmetrical about the diagonal. The upper left quadrant shows the "Big 5 plus Notre Dame" matchups, and the bottom right matchups between teams from the "group of five."
Of more interest from a ratings standpoint is how well-connected the field is at pathlength two: opponents and opponents' opponents. For 2018 by the end of the regular season more than half the field is separated by more than that.
Of course, the main reason division 1A is not as well-connected as it should be is the rule that allows games against 1AA teams to count every year. The sport needs some such games for 1AA to stay financially viable. But ever since the "once every three years" rule was dropped 1A has become less and less well-connected. Just how much that affects schedules in 2018 can be seen from the pathlength two graph for all of division 1:
It would not be hard to tell the 1A/FBS quadrant (the northwest) from the 1AA/FCS quadrant even without the colored lines. From a ratings analysis standpoint, the games in the northeast quadrant (reflected by the diagonal to the southwest) contribute little to connecting either 1A or 1A.
The last row shows all of the FCS games which as usual are all road games for the 1AA team. Each is a lost opportunity for the analyst and fan. The upper left shows all of the top-n matchups in the regular season schedule, most of which are conference games. The schedule by week and how highly the opponents are ranked can be found at theRank-Based Interest Factor page.

There are 38 interconference games between teams from the "Big5" plus Notre Dame, and 100 between the Big5 and "group of 5." How many Big5 vs Big5 games could there be? Turns out if we just count the number of pairs where the teams are from different Big5 conferences and both either have an open date or 1AA opponent we find over 400 "unused" opportunities for 48 spots, including 34 top25-top25 matchups. Here's the breakdown by week for the Big5 teams:
Good scheduling should not be as hard as some would have us believe.
