Keeping defenses guessing is half the battle when you try to move the ball against them, unless you have a horse that needs fed.
Such was the case for the 2015 Ohio State Buckeyes. Ezekiel Elliott was the animal that demanded touches early and often throughout the course of the season. If he didn't get the ball, the offense often struggled, especially with Urban Meyer trying to figure out what to do at quarterback for more than two months.
It all came to a point to a disappointing 17-14 loss at home to Michigan State, an outcome that kept Ohio State out of the Big Ten Championship Game and ultimately the College Football Playoff.
