There is a body of work to consider. I don't believe anyone who "hates on" Roy does so because of an agenda or whatever. Like most of us, those folks want to see this club and this defense do well. I can say the same for those who love them some Roy Williams.
Like most, I have my Roy episodes. I try to call 'em like I see 'em. I believe the guy played very well vs the Packers. He has been solid for the most part, IMO.
What I do like about the deep-third of this defense, is the limitation of big plays, particularly in the passing game. Receivers will run free a lot due to restrictions on DBs (non-contact rules), but this unit has done a really good job in keeping people in front.
That's job one for the safeties. Roy should get credit for some of that, too.
