Show was tremendous in every thing he did on this RAW. His promos, believability, perfect work. He SAVED this show two weeks in a row now from "worst of all time" material. His promo on Clay, then the spear and the beatdown was a heel from another era, great booking from WWE for once but amazing execution from Show. Glad that he can show what an awesome performer he is.
As for the position, Big Show is the top heel and a main eventer since the day he got into the business, of course he's closing the show.
