I'm not overly confident in it, as I'm just not sure they have the secondary to hold up against the better QBs in the league, and the lack of depth at WR will probably hinder their ability to keep up.
As I said in the game thread, I'm not sure if the likes of Austin, Jefferson and Williams would even see the field on a lot of other teams.
The front 7 on defense is fairly solid and Russ and even the OL have had their moments, but there are some pretty glaring weaknesses at WR and CB that might be hard to overcome in the post season, as I just don't have a lot of confidence in the coaching being able to compensate for them.
