Sting vs Taker wouldn't be the main event, for as long as Brock and Rock are scheduled to be at Mania 31, you can bet your house one of those 2 are in the main event. If Sting does sign, I do see them doing the match at 31. The only chance they'd get to close the show would be if Taker was retiring. Otherwise there's no chance.
Rock has said he is going to do WM31 and is rumoured to face Lesnar there. Rock v Brock, careers on the line. :gusta:
