If he had more help, he would be more durable. He has to take the vast majority of the touches and snaps at RB because we don't have a reliable option other than him since Ingram left. Hill took some of the load this year but then he got hurt.
Is that the excuse for his entire career going back to college? He came into the league with durability concerns. It's not a popular opinion since he's a fan favorite, but he's not the most durable RBs and fans come out with pitch forks anytime someone says something true, but not glowing about AK.
