Josh Kaddu, Oregon
I thought about lumping the linebackers together, but this is one area where there seem to be at least some lines drawn (although blurry after Lawrence Timmons moved outside and then back in last season).
There's no apparent or immediate need here. James Harrison and LaMarr Woodley seem primed to team up for a big year in 2012 if both can stay healthy. That's bad news for the rest of the AFC, particularly the quarterbacks they'll face.
But behind them is only Jason Worilds and versatile Chris Carter. Worilds may not be able to be kept if he reaches free agency before the current starters reach retirement. He's got too much skill. Carter doesn't seem to be future starter material.
Josh Kaddu might be. He's a little raw, but he'll be a good guy for Dick LeBeau and Keith Butler to work on in the coming seasons if the Steelers feel the need to add to their depth.
