On Wednesday morning, the bickering tribes of college football came together to wish Jerry Kill well. Kill, Minnesota’s fifth-year coach, has epilepsy and recently had seizures, so during the week he announced his immediate resignation because of concerns about his health.

But if Kill’s departure seemed cut and dried, seven other head-coaching changes in the Football Bowl Subdivision this season did not.

Seven midseason vacancies — including Kill’s, and not including that of Illinois’s Tim Beckman, who was dismissed one week before the season opener — is the same number as the previous three seasons combined, according to Stats L.L.C. It is not uncommon for there to be no coaching changes atop the more than 120 F.B.S. teams until after the regular season is complete.

Three coaches — Dan McCarney, from North Texas of Conference USA; Randy Edsall, from Maryland; and Al Golden, from Miami — were fired simply for not winning enough. Beckman and Southern California’s Steve Sarkisian faced questions about their personal conduct. Central Florida’s George O’Leary, after an 0-8 start, resigned from the program he was integral in building. And Steve Spurrier walked away from South Carolina after beginning 2-3.
