Ed Carpenter Racing, Chevrolet. JR HILDEBRAND. D. Not including the Phoenix and Iowa races, JR Hildebrand’s season would have been clearly deserving of an “F” grade, as he had no top 10 finishes in the other 15 races. However, the fact is, those races were his best two races, and not only did he finish in the top 10 in both of them, but he finished on the podium in both of them, so he is saved from getting an “F”. He even tied his career-high finish of 2nd place at Iowa, and he didn’t hit the turn 4 wall to secure it.. No. 21
