5. Mackensie Alexander
Alexander is one of three Clemson players in the top five and he is deserving of this number five spot, even after just two years in the college football ranks. He has proven that he can play at the next level and has great length, which attests to him not allowing very many completions.
Alexander allowed only 29.6 percent passes thrown at him to be completed, which is a great feat for any player to accomplish. He loves to mix it up and will play anyone through the whistle.
