If you could bring back one retired or dead wrestler to WWE who would it be and why?

Personally I would bring back Eddie Guerrero, or else Chris Benoit. Both men did a lot for the business and their WM XX wins and celebrations will forever be remembered. However, even though both guys won their titles at WM XX they were pushed down the pecking order again, with Eddie going back to mid-card and Benoit playing a supporting role in the HHH-Eugene storyline. Therefore I would bring both of these guys and have them stay on the top where they belonged.
