The top defenses provide a nice advantage in college fantasy football, with some of the more well-known schools, like Alabama and Clemons, high in the rankings thanks to simply having the best players. Other non-Power-5 schools, like Boise State and San Diego State, provide consistency in smaller conferences, and that's why these defense/special teams units are able to make their way into the top 15 of the 2018 rankings.
