There's still a lot of football left to be played. If Rex is any kind of a coach (and I personally don't like the Ryan brothers as coaches) he will get this team turned around. Believe it or not, they do have some talent. Sure, Revis is out for the year but every team suffers from injuries so that's really not a valid excuse to suck.
This is on Ryan. This is where a real coach, a real leader, makes the difference between a winning season and a chaotic mess.
