There were many critical plays in the CFP Championship Game that proved to be the difference between Miami winning its sixth national championship and Indiana finishing 16-0. When Dylan Joyce had his punt blocked and the Hoosiers recovered it for a touchdown, that was definitely a critical that ultimately proved to be the difference in the game.
The special teams unit shouldered the blame for the loss because of the blocked punt and an earlier missed field goal. But football is a game of inches and, as the videotape showed, Miami was mere inches away from a major special teams play that would've resulted in a Hurricanes touchdown.
