Re: Out of these 3 matches which would be the biggest at Wrestlemania
I don't know if you are talking about this mania or ever, so I will do both.
Hulk Hogan vs Stone Cold Steve Austin
current: no way, Hogan can barely walk and Austin knows better
ever: I would say yes, both these guys at the peak of their popularity would have bigger buys than any other option
The Rock vs John Cena
current: probably biggest potential if the Rock would come back, problem is that he would have to go over and that isn't good for Cena.
ever: second to the above
The Undertaker vs Sting
current: second biggest because both can still go somewhat. these two would have the biggest buildup, and can do the mind games like no other
ever: 3rd to me in the list because the 4 above probably have bigger marketable names.
