One more thing, and this is just what I heard. I'm not sure if it was ever stated why the Rams released him, and I'm not sure if this was the exact reason why the Rams let him go.
In one practice the receivers were told to go to one area of the field, and the DBs to another area. Titus started to go with the DBs. So a coach, thinking that Titus must have heard wrong, simply told him that he was going to the wrong area. So Titus tells the coach that he's playing DB today.
I guess that didn't fly with the Rams.
