Now that college football has a four-team playoff, it is less important to win every game during the season. But it sure helps if a team does go undefeated, and — according to ESPN's Football Power Index — seven teams have a legit shot to run the table during the regular season.

FPI simulates the regular season 10,000 times, and Oklahoma, the No. 3 team in the AP Top 25, has the best shot to win all of their scheduled games. The model gives the Sooners a 17.7% chance to run the table. The Sooners are also being given the best chance out of the Power Conference schools to win their conference at 65.4%.

Florida State is second at 42.1%.

Florida State is the only other school with at least a 10% chance to go undefeated. Overall, seven schools are being given a legit shot — at least 5% — to have zero losses when conference-championship games begin.
