Maybe the Steelers signed Plax to be a personal consultant to Mike Wallace.
Plax to Wallace: "Listen dude... you should have just accepted the Steelers offer of ~50/mil. The Rooney's aren't playing around...Oh and by the way.. The lack of effort, the dropped passes, etc definitely isn't making you any richer. If you go to a different city, bad things will happen. Don't shoot yourself in the foot or in my case, the leg."
