After the Chargers said goodbye to Melvin Gordon, adding backfield depth in the draft became a priority, and they wound up selecting Kelley in the fourth round. A downhill runner out of UCLA, he has the power and balance to hammer through contact, and, with a 4.49 40, good speed once he finds open space. His lack of vision, elusiveness or receiving skills make him unlikely to become a true three-down back, but as a complementary option behind new starter Austin Ekeler, Kelley could thrive between the tackles and in short-yardage situations. The rookie will compete with holdover Justin Jackson for those backup touches, and Kelley might be a better fit for the role, given that he's about 15 pounds heavier at 5-11, 212. With Ekeler relatively unproven in a full-time role, there could be a decent number of snaps and carries available for whoever emerges as the Chargers' No. 2 back. Read Past Outlooks
