... one of the weakest units on the team. They had lost cornerback Bryant McFadden to free agency and All-Pro Troy Polamalu to injury for most of the season. Flash forward one year and the Steelers made a trade to re-acquire McFadden from the Arizona Cardinals and Troy Polamalu is healthy entering training camp. All of a sudden, a potentially weak group is looking relatively strong once again. The Steelers secondary will be looking to rebound from their poor performance in 2009 when they allowed 22 passing touchdowns while making only 12 interceptions while finishing 17th against the pass. The return of McFadden and Polamalu should help as well as the potential emergence of the young talent they have at corner.
