If we signed Manning, then we MIGHT consider signing Clark to a 1 year deal (only at a good cost), but probably so he can show Clay how to play the position the way Manning likes it. Clark & Clay are pretty much the same size and skill set, so I don't really see the sense of having Clark around more than 1 year, if at all.
But my money is on Clark not coming to Miami- even if we do get Peyton
