6. Kane
Yes, we are now coming to the really likely ones. There is no doubt that there is a sizable contingent amongst the IWC who would love to see Kane and Undertaker both go out with one more match at Wrestlemania against each other. There is no doubt that there are many pros to this idea. Firstly, the two can deliver in the ring and know each other's move sets inside out- so the idea of bad ring chemistry is almost impossible. Secondly the angle is easy enough to write as the two brothers have enough history to delve into. Finally there is no doubt that both superstars deserve a big send off and it would be great to see them in one of the big matches before they finish. The main problem with this is that, frankly, we've seen this before and while it would be nice as a sort of nostalgia thing for the Wrestlemania event, there are plenty of other candidates for the match that may be able to pull more tickets into the gate. Still, it's a scenario that remains an outside chance.
