Williams has been waived by the Cardinals, ESPN's Adam Caplan reports.
Williams joined Arizona in 2014 and rushed 80 times for 388 yards since then, posting an impressive 4.8 yards per carry while scoring once for the team. However, with David Johnson, Chris Johnson and Andre Ellington definitely ahead of him, and Stepfan Taylor (knee) also around, the Cardinals simply chose to focus on building depth at other positions, thus making Williams the odd man out at running back.
