– It’s said that CM Punk was happy to go heel. The story is that Punk realized he was never going to surpass John Cena as the #1 babyface but the #1 heel slot has been wide open.
On a related note, Randy Orton has made it clear he wants to be a heel and can perform as a top heel. The problem with that is WWE won’t turn him until they are fully confident in Sheamus drawing as the top babyface on the SmackDown side.
