Hue Jackson gave him autonomy with the defense, there's actually some decent young players, they are about to sign Jamie Collins, etc. Mostly, I'd say that he's got the opportunity to control an entire side of the ball. Williams has a reputation for changing cultures on the defensive side of the football and is a mentor to a lot of players when they are placed on his squad (he said he gets about 200 calls on Father's Day). He's been a very good NFL coach since 1990 who has played against Hue's offenses enough to know that he's the type of guy he wants to work with (his words). I know where you're going with it, but some people don't just go easiest route.
