What happened: The fourth-round pick led Las Vegas in exhibition rushing. His three game totals were 63, 56 and 49 yards.
Why it matters: Washington turned limited volume into consistent gains before the regular season. Week 1 will test how that efficiency translates when the games count.
By the numbers: Washington gained 168 yards on 23 carries, averaging 7.3 yards per attempt. His longest run covered 53 yards, and he finished without a rushing touchdown.
What to watch: His carry count, targets and red-zone work will define his first regular-season role.
