What do you think of the Steelers getting Mendenhall and Sweed?

I was shocked when I heard my team draft Mendenhall, and excited when they drafted Limas Sweed. With a two back system, a great RB in Willie Parker and a great future back in Mendenhall, not to mention a tall Limas Sweed, the Steelers lineup will look like this: Santonio Holmes, Hines Ward, Limas Sweed in the slot, Ben Roethlisberger behind center, and Willie Parker rotating with Rashard Mendenhall. If they can get a good offensive lineman in round 3, can this be the draft that turns Pittsburgh into a powerhouse again?
