Richardson appeared to have the makings of a late-round gem as a rookie in 2012 when he rushed for 475 yards and averaged 4.8 yards per carry in a backup role to Steven Jackson.
He won the starting job as Jackson's replacement this past training camp but suffered a toe injury against Arizona in the opener and never was able to get back on track. He finished with 215 yards and an average of 3.1 yards per attempt while playing in just eight games.
Richardson was surpassed on the depth chart by Zac Stacy who is currently listed as the starter, and the Rams also drafted Tre Mason in the fourth round to add to their backfield depth. The Rams also have Isaiah Pead and Benny Cunningham on the roster.
In an ideal world, Richardson could have worked as a change-of-pace back with limited carries but his inability to make defenders miss in the open field or break tackles made him less than ideal as an every-down back. He was scheduled to make $581,474, and his release will save the Rams $558,526 in cap space.
