This is gonna be a write up of their upcoming match looked at from lots of perspectives:
First off, SUBMISSIONS:
this is a category Kane is very lacking in. He has some bearhugs and nerve holds and chokes, but he is not the submissions master the Undertaker is. Undertaker can pick a leg or arm and bar it. He can do chokes, holds, all that jazz. Kane can't win with a simple chinlock or choke, but Undertaker has 3 holds that can take out opponents, his Hell's Gate (current favorite), his Trinagle Choke, and his Dragon Sleeper.
Who would be the weirdest person you can think of who likes wrestling? I think a weird one would be the Pope for a start. Still, with quite a few wrestlers being religious, I suppose he might watch it...
