In college football's playoff era, only five programs have notched perfect seasons en route to a national championship with Michigan being the most recent in 2023. But now, the parity playoff expansion has brought to the sport -- and the possibility of a team playing as many as 16 games on their way to the title game -- the likelihood of an unblemished campaign is considerably low.

College football is officially back. At 12 p.m. ET, the Week 0 schedule will kick off with an exciting showdown in Dublin, Ireland. Iowa State and Kansas State have the honor of playing in the first game of the season.
