For the nit-pickers on this board, yes I know Rooney is both CEO and Chair.
Once they get to the point of crossing their last few 't's and dotting their last few 'i's, then I believe Mr. Rooney will step down as CEO.
Though it is his vision and drive that will have carried this company over the finish line, I believe him to be wise enough to recognize the benefits that the image of a shiny, new superstar CEO will have on the companies perception in the marketplace.
