Who was there that met position of need and value, that was likely to still be on the board if the Steelers traded down? Hampton went immediately after the Steelers pick, Harmon was the last first round worthy DLine on the board and may not have been around if the Steelers traded down, and if you think Dart was first round worthy, they wouldn't have got him with a trade below 24, and Giants may have traded further up if the Steelers did trade back to 24. I can't really see anybody else left on the board at a position of need that was worth sacrificing Harmon for.
