Expand the playoff team count a bit and all the Massengill Feminine Douche bowls go away.
The CFP expands to 12 next year, but I wouldn't count on a decline in the number of bowl games. In fact, new bowl games in Cincinnati (Chili) and Chicago (Chicago) are in the works. Additionally, a reduction in the number of bowl was predicted when the Bowl Coalition, Bowl Alliance, BCS, and first iteration of the CFP were all announced. When the Bowl Coalition was formed in 1992, there were only 18 bowls. Now there are 43 bowls, including the CFP games.
While many, if not most, schools make money from bowls (if only through profit sharing within a conference), the biggest single benefit from coaches' point of view are the 15 additional practices bowl teams are allowed by the NCAA. Most coaches, especially those outside the CFP, use those practices to get a head start on spring ball and the next season. Ironically, the teams who need more practice the most, those who had losing seasons, don't get those additional practices. Change the rules to allow all FBS schools 15 extra practices at the end of the season and the lure of minor bowls is less.
