1. 2020 Alabama (13-0)
CFP result: Beat Notre Dame 31-14; beat Ohio State 52-24
The Crimson Tide had the Nos. 1, 3 and 5 finishers in the Heisman voting. They played one game decided by fewer than 14 points. They bested an SEC-only schedule by an average of 30.2 points per game. Their defense struggled early but allowed only 15 points per game after mid-October. This was the best Nick Saban team ever and quite possibly the best of the 21st century.
Best team ... from the best coach ... with the best dynasty of the 21st century (at the very least)? Sounds like the best team of the CFP era
