Chris Carter of the Pittsburgh Post-Gazette, hosts the Locked on Steelers podcast.The Pittsburgh Steelers still have a big need at center. General manager Omar Khan said trading for a center is a possibility, and Chris Carter thinks it might be a necessity. But who are realistic options? And are any of them good enough to mean they don't need to draft a center high? Also, Chris reviews the three recent free agent signings of Quez Watkins, Ryan Allen and Dean Lowry, and what they mean for the roster and the Steelers' draft plans. Speaking of draft plans, the signing of Watkins means the Steelers are most likely not going to make a big move at wide receiver via trade or free agency. And that means, there is a high draft pick coming at the position.CALL INTO THE SHOW AT 412-223-6644 or if international, e-mail your audio message to LOSTEELERSTOPICBAG@GMAIL.COMFollow Chris Carter on Twitter: @CarterCritiques.Theme music is 'Soul Kick' by Ceddy P, and 'Too Easy' by Nerdboy.
