Problem about the Saints is that they don't have a decent tight end, and Antonio Gates was like Drew Brees' favorite target.
They are set at WR with Stallworth and Joe Horn; I really think that Joe Horn can look forward to a big year this season, he still has something left in the tank. If Keenan was productive with Brees, Joe shouldn't have a problem finding success with Drew as well.
The Saints also need help with their offensive line; they don't create holes for their running backs, but they give Brees enough time on the pocket to create a play.
The Saints defense is just a disaster. We're talking about probably the worse defense in the league.
