15. Caleb Pyle - Bolivar - JR: A big PR landed Caleb Pyle just 3 spots off a podium spot in 2016. He entered the November classic with only one career race under 17:35, but dropped a 16:59 and just missed a medal. In the spring, Pyle added 4:50 and 10:10 personal bests on the track and should be another key contributor for the Bolivar Liberators as they return 5 of their top 7 from their 6th place 2016 team.
