bowl eligibility

66 "FBS" teams had at least 6 wins against other FBS teams during the regular season; these teams are eligible to go to bowl games.  (Teams can count one win against an FCS team for bowl eligibility, but that would have involved extra work for me, especially as I'm reusing code I wrote years ago.  Laziness also led me to declare any game in December "post-season".)  Mississippi only won 5 games against FBS teams, but played fewer than 5 games against FBS teams that aren't bowl-eligible; they beat 2 teams that are bowl-eligible, and only lost to one that isn't — Arkansas.  If I make Mississippi eligible, then Arkansas beat one bowl-eligible team, and lost to no ineligible teams.

If we adopt this as the rule — you're bowl-eligible if you win at least 6 FBS games, or if you beat more teams that are bowl-eligible than lose to teams that aren't, recursing as necessary — there are 14 additional teams that gain bowl-eligibility:  Utah, Texas Tech, Mississippi, Minnesota, Nebraska, Florida St, Colorado, California Vanderbilt, Tennessee, Syracuse, Maryland, Florida, and Arkansas. the last six in particular only had 3 FBS wins each, but since almost every FBS team they played was bowl-eligible, they get strength-of-schedule credit.
