I've come to the conclusion that the only reason HHH won against Lesnar at WM is because Brock wanted a Wrestlemania payday.
Well think about it, who makes the most money in matches? The losers. You are paid more to lay down for the other guy so they look good (and so you don't have any motivation to be in business for yourself). Cena was already occupied, so who was left?
I think Undertaker would have been a smarter choice, but that's just me.
I could DIIIIIIIIE! Or worse, DIIIIIIIIIIIIE!
