Despite rumors that he wasn't happy with the move, Donovan McNabb claims that the signing of Michael Vick isn't a threat to him. The Eagles inked Vick to a two-year deal on Thursday. "There's no threat for me," McNabb said at a press conference after Thursday's preseason game. "There's no threat for [Kevin] Kolb. It's an opportunity to add another weapon to our offense, and our team." However, former Philadelphia lineman Barrett Brooks, who covers the team for 97.3 FM in South Jersey, believes that the signing will lead to trouble in the locker room. "McNabb is being a pro," Brooks said, "but this makes him have to put up or shut up. He has no comfort in being the Eagles quarterback, if he messes up one time the whole city will be calling for Vick. Point blank."
