Isaiah Spiller

A fourth-round pick in this year's draft, Spiller steps into a big opportunity with the Chargers as the likely backup to Austin Ekeler. The Texas A&M product showed strong vision, balance and elusiveness in college, but he lacked physicality both while running between the tackles and when taking on defenders. Spiller also has some work to do to become a reliable option on passing downs, though that's not surprising for a Day 3 pick. The best thing he has going for him heading into training camp was weak competition for the No. 2 role behind Austin Ekeler, as Justin Jackson didn't re-sign with the Bolts this spring and neither Joshua Kelley nor Larry Rountree has shown much in the pros. It's possible that Spiller could take over the work that was split between Jackson, Kelly and Rountree last year - a total of 137 carries and 33 targets - down the road, but complicating matters in the short term is that Sony Michel joined the Los Angeles backfield ahead of Week 1.
