The other thing about having a D that can cover up mistakes is it allows a rookie QB to grow into the game. EJ fudged up and he will fudge up again like any rookie. Having a D that can bail you out and then give you a chance to win is awesome.
Byrd is very good. It's not about whether he 'fits'. It's about whether the way pettine uses safeties if you can get good production at a smaller cap number and use that cap elsewhere for like...linebackers.
Sometimes, we say things with an added flair. You could have simply, stopped, said hey, we're having a failure to communicate and what I am saying is being taken out of context. You decided to double down. Expect criticism.
You'll see the Bills are doing much more pre-snap than under wanny's defense which likely caused enough confusion to let Dareus be 1 on 1 when the offense had the extra man.
