The Steelers are always going to find answers under the brilliant Dick LeBeau, but they have to get younger, particularly up front, and they know it. Poe is that rare zero-technique centerpiece to a 3-4 defense, the guy who simply eats up blockers and frees up the linebackers. If he develops, Poe can be the heir to Casey Hampton in the middle of that scheme, and these guys are just really tough to find. The value lines up as well.
The Steelers have always been a defense-oriented team. They could use the upgrade to their defensive package and if he can be the next great nose tackle in the Steelers 3-4 scheme, the linebackers could wreak even more havoc than they already do.
