If you look back, Brooks threw for 18 TDs the first half of the season until he hurt his shoulder and then threw only 9 to finish the 2nd half. The whole offense fell off b/c of it. Losing so many games by 7 pts or less and the last three to miss the playoffs? Who was the only team to beat TB last season? Saints!
Of course the real matter is how long will Brooks stay healthy. If he does, I'm sure the math can be worked out quite easily on what kind of season the Saints O could have this year. I put them in the top three.
