Melvin Gordon's holdout last season opened the door for Ekeler to show what he could do in a consistent lead role, and he racked up 490 scrimmage yards and six touchdowns in the first four games before Gordon slunk back on to the roster. Ekeler's usage fell after that, but he still had moments to shine later in the year, including a 213-yard eruption against the Jaguars in Week 14. Heading into his fourth NFL season, the undrafted rookie out of Western State Colorado seems set as the Chargers' new No. 1 back with Gordon now a Bronco, giving Ekeler his chance to dispel the notion - once and for all - that he's only a passing-down specialist. His agility and low pad level have always made him difficult to bring down on first contact, and his broken tackle rate was 14th in the league among backs with at least 100 carries - comparable to bulky runners like Derrick Henry and Mark Ingram. Ekeler may need to find extra production on the ground, however, as Philip Rivers' departure for Indianapolis will give the Bolts offense a different look this season. The scheme won't change with offensive coordinator Shane Steichen returning, but Rivers' penchant for flipping passes to his backs is legendary - something that neither Tyrod Taylor nor Justin Herbert is likely to match. Ekeler will hope to make up for it with additional rushing volume and potentially more snaps, taking the lead over Justin Jackson and rookie fourth-round pick Joshua Kelley in the Chargers backfield.
