The four-team format has been heavy on uncontested games in the semifinals but has featured much tighter games in the championship. Even though uncertainty is aplenty at the start of each year, there has not been a ton of parity in the Playoff.
Alabama has made it to four of five Playoffs thus far, winning it all twice. Clemson has made it each of the past five years, Oklahoma has been in four times and Ohio State has qualified thrice. The Pac-12 has the fewest bids of any major conference with two in five years, while the SEC and ACC have had at least one representative each season. The SEC became the first conference to have two teams (Alabama and Georgia) in the Playoff in 2017.
Here is a look at the past winners and brackets of the Playoff over the previous five years and counting.
