When did the Steelers sign CB DeMarcus VanDyke? Who did they cut from their roster to make room for him. I could have sworn he wasn't on their original 53-man roster. Have I been living under a rock or something? I didn't see any news articles on it, didn't see any tweets, didn't see him in the preseason? What gives? I believe he was a Raider last season. Can someone shed some light on this for me?
