Game over
The 2016 Tigers beat then-#3-ranked Louisville and then-#12-ranked Florida State as part of a 9-0 start before losing to Pitt. Bounced back to win every game thereafter, including the ACC Championship Game over then-#23-ranked Virginia Tech, the Fiesta Bowl and CFP Semifinal over then-#3-ranked Ohio State, and the National Championship game over previously unbeaten and then-#1-ranked Alabama. Clemson finished the season ranked #1, obviously.
