When we signed him, I wasn't really impressed. His highlights suggested that he was a short yardage back with no speed and minimal impact in the passing game. I didn't pay attention to the TC threads or highlights, but watching him in preseason confirmed my thoughts about it. The Oline was bad and Titans has a good run D, but don't expect much out of Williams.
Also Miller looks to be an exact clone of Williams, but I believe Miller has a bit more speed.
