Warrick Dunn underrated? You do know how badly the Falcons over-paid for him when he was a FA a few years ago, right, I'd say they overrated him. He hasn't even cracked 1,000 yards since 2000 when he was still in Tampa, and that was his carreer high with 1100. Plus he isn't getting any younger at 29 years old, he spends more time on the IR than on the field.
I like the guy, but I would say he is FAR from underrated.
I also disagree with you saying Simeon Rice and Booger McFarland are the most overrated players at their posistion, I would say they are among the best at their posistion. They will prove that with Sapp's departure this season.
But everything else looks pretty good.
