5. 2017 Alabama (13-1)
All-Time Season Score: 26.6286
Easily the weakest of all the College Football Playoff era national championship seasons – and that’s among all teams – the Tide lost to Auburn, didn’t win its own division, and caught a massive break when an unbeaten Wisconsin lost the Big Ten Championship to Ohio State on the final drive.
But when it got into the CFP … boom.
To be fair, Bama beat eight teams that finished with a winning record, destroyed Clemson in the CFP semifinal, and pulled off the epic finish when Tua Tagovailoa hit DeVonta Smith on a 2nd-and-26 touchdown pass to beat Georgia for the national title.
As good as the offense was, this was still a Nick Saban defense. It allowed ten points or fewer in nine of the 14 games, finished No. 1 in the nation in total D, No. 1 in scoring D, and No. 1 against the run.
