There are 20-plus college football teams still undefeated four weeks into the 2019 regular season. That number is sure to go down in the weeks to come, though.
By the end of the season, only a couple of teams will have yet to lose a game.
ESPN's Football Power Index believes four major programs have a chance at running the table.
Clemson (4-0): 65.9 percent chance
Alabama (4-0): 25.4 percent chance
Ohio State (4-0): 24.2 percent chance
Oklahoma (3-0): 19.7 percent chance
