We've reached the midpoint of what has been an unpredictable 2021 college football season.
Already, 40 ranked teams have lost, including defending national champion Alabama on Saturday night. That's the most in the first six weeks of the season in the AP poll era (since 1936), according to data from ESPN Stats & Information.
And the number could be even higher. On this past Saturday alone, five other ranked teams trailed heading into the fourth quarter but rallied to win -- Iowa, Oklahoma, Michigan, Notre Dame and Wake Forest. That's the most such teams on one day in 15 years.
