Sure the thought of taking Poe at 24 seems to be the consensus, but I'm not sure it makes a lot of sense. The Steelers are tight against the cap, and will be for a few years to come. They've yet to sign Wallace, look to be in the same situation with Brown next year, and have restructured so many deals the salary cap is becoming a bigger nemesis than Baltimore or New England.
Not to mention age. They're old at ILB and NT, and getting there at safety. They still need help/depth on the O-line, and have no No. 1 RB to start the season. Trading back will give them a handful more picks in this years draft, and maybe one or two next year, depending on how far back they go.
They can get a pair of second round talent in the trenches, Ta'Amu (NT) and any second round guard. They could possibly add a 3rd rounder, where the Steelers haven't been bad the past few years. The Steelers always draft quality, this year they need to take a page out of The Hoodie's playbook and draft quantity. I have faith in Colbert to find talent whether its the 1st or the 6th round.
With an influx of young, cheaper, talent the Steelers can let some guys go. Next year, when the Steelers will find them selves another $25 million over the cap they'll be able to rely on their 2012 and 2013 draft classes to pick up the slack after a series of cuts/releases.
