I think only 3 teams ranked in the top 5 of the 4 major statistical catagories for passing offense. The Titans, Colts and Vikings were the best passing teams in the NFL last year when you break down the numbers. The Titans were best in TD/INT of the group and YPC, while they ranked in the top 5 for total yardage and Steve McNair is still on top of his game. He has only missed 3 of his last 64 reg season contests although every year I keep reading about how he won't hold up. Of the three best passing attacks in the NFL, two are in the AFC South, so being on top of this division will not be easy.
We have improved, but now we are as good as average teams. This is a tough league.
