First, let's dispense with the obvious: Of course the Saints need to do their best to continue their recent roll of draft hits and will be looking to improve the depth chart at receiver, linebacker and defensive tackle. But the larger key on a team with a number of Pro Bowlers in their prime -- especially on the offensive line -- is to work out a sensible contract with Drew Brees while trying to retain as many key free agents as possible. The Saints have eight players headed for the open market who played more than 50 percent of their snaps last year, including three in the secondary. That will make life tricky for general manager Mickey Loomis, who has made it clear he wants Brees back. The Saints have enough young talent to worry about the post-Brees future when they get there. For now, it's all about retaining a roster that has been good enough to win a Super Bowl the last two seasons despite the painful playoff exits.
