Three Dog Night says one is the loneliest number, but NCAA football coaches would likely tell you six.
Why six?
Six wins means your team is headed home after their final regular season game. No bowl. No extra weeks of practice. Seniors are done with their careers and underclassmen clean out their lockers only to suit again next spring.
Last year, a handful of six-win teams did get into a bowl, but that was only because there weren't enough seven-win teams to fill the 80 allotted slots in 40 bowls. The NCAA nipped that problem after they put a moratorium on new bowls for the next three years.
