The lesson? Things change fast in the National Football League.
On Saturday, Morris took to Instagram to talk about his four years in Washington.
Morris, 27, began his career with three consecutive 1,000-yard rushing seasons -- including a whopping 1,613 yards and 13 touchdowns as a rookie -- but he slumped to a career-low 751 yards and 3.7 yards per carry in 2015. Morris won't get a hugely lucrative contract in free agency, but he should be able to find work without a problem.
