2. 2009 Alabama (14-0)
All-Time Season Score: 30.100
It was Nick Saban’s first and only unbeaten national championship before the 2020 run, and this might have been his most dominant defense ever.
The 2011 version was a wee bit more consistently amazing, but the 2009 team allowed just 164 points on the season, beat an unbeaten national champion Florida – with Tim Tebow, Urban Meyer, and a loaded squad on both sides – 32-13 for the SEC Championship, and stopped a 13-0 Texas team led by Colt McCoy for the BCS Championship.
There were a few fights along the way – Auburn made it fun in a 26-21 Tide win, and the 12-10 victory over Tennessee was way too tight – but Bama ended up beating ten teams that finished with winning records and turned it on when it absolutely had to at the end.
The only thing missing was the offense that the best Nick Saban national championship team of all-time brought.
