Iowa will crack the top 25
A.J. Epenesa
When looking at Big Ten programs that are poised to have stronger than usual recruiting performances in 2017, the Iowa Hawkeyes top the list. The momentum started when the Hawkeyes rolled through the regular season undefeated in 2015 and went on to play in the Big Ten Championship game and the Rose Bowl. Positive on-field performances have the biggest effect on the current group of juniors, because seniors largely have already formulated their opinions. Iowa has already capitalized on that momentum by building a strong core for the 2017 class with four in-state commits and most recently secured the commitment of four-star legacy prospect A.J. Epenesa, who is ranked as the No. 27 player overall in 2017. Iowa has not signed a top 25 class since 2005 and its classes have ranked outside the top 40 each of the last five years, but in 2017 it has the recipe to move back into top 25 territory.
