Incorrect. He played on a great St. Louis Rams D with Donald, Chris Long, Jackrabbit Jenkins, Rodney McLeod, Trumaine Johnson. They were a top 5 defense who were always terrible on offense because of a carousel of bad QBs, and Jeff Fisher the coach.
Notice "team". Not "Defense". The Rams defense in those times was just as good as ours. They were overshadowed by 2 better defenses in their own division at the time, but that doesn't take away from them and the fact they were Top 5 on defense and Bottom 3 on offense.
