What happened: Washington finished the preseason with 168 yards on 23 carries. He gained 49 yards on eight attempts in the finale.
Why it matters: The production gives Las Vegas another viable backfield option as the regular season begins. Converting that showing into steady snaps would deepen the Raiders' rotation.
By the numbers: Washington averaged 7.3 yards per carry, with long runs of 53, 33 and 13 yards across three games.
What to watch: Watch his snap share and carry count in the opener to see whether he earns a defined role.
