DC Steve Spagnuolo said he wanted competition at the nickel CB spot and he believes he's done that with the additin of CB Elbert Mack on Tuesday. "He's a feisty corner," Spagnuolo said. "Every time we turned the tape on he was making a play. He is flexible in that he plays the outside, and he has played the nickel spot. That's an interest of ours." CBs Johnny Patrick and Marquis Johnson should be Mack's competition at nickel.
