Everyone knows those stats are overrated because they are related to each other.
Not only that, but this is a pass-first league and the Bucs play in perhaps the most pass happy division in the league. The Saints and Falcons don't even pretend to run the ball anymore. The Panthers dynamic duo of Stewart and Williams has all but disappeared as well.
The Bucs run D is ranked #1 because 8 of their games come against teams who don't run the ball, which is why they give up so many passing yards.
The Raiders had this same stat ranking a few years ago. The Bucs have some good players, and Goldson and Revis are great additions and upgrades, but they are a few more good players away from behind one of the league's best defenses. They really need an elite pass rusher.
