Analysis: Williams is a stout run-stopper who played mostly nose tackle in Arizona's 3-4 defense. He had the seventh best run stop percentage last season, according to Pro Football Focus. He played mostly on run downs and was not used much as a pass rusher and has just two sacks in 70 career games.
