...the next longest running undefeated streak at Wrestlemania belongs to Rob Van Dam. He's 4-0.

However, The Miz has the opportunity to tie that this year if he beats Wade Barrett, as he's next with a record of 3-0.

Whoops, nevermind the bit about Miz tying RVD this year! Completely missed him and Barrett getting bumped to the pre show. I'm pretty sure that doesn't count. Maybe next year...

yeap, i knew that, and before him was edge (6-0), but lost against the undertaker
