Aw come on, you know what he meant, if we all picked out poor grammar, be it one word in a paragraph or half a post this board would be filled with twice as many posts.
Back to the topic, I believe Shawn Michael's is "Mr.Wrestlemania", somehow he always rises to the occasion, especially the ladder match against Razor Ramon, which in my opinion, was way ahead of it's time in terms of moves and creativity and what-not.
I think Hogan, as much as I hate him, has to be given credit, because at the end of the day, the hype that surrounds his Wrestlemania is second to none, and the fans always seem to get into the matches, regardless of the quality, and although we like to see great matches, the fans who are there live I'm sure want to see Hogan going through the motions of all his signature moves and taunts, which adds to atmosphere.
The Undertaker I can understand being considered, I loved his match with HHH a few years back, although some of his matches at WM have been poor. But fair play to him/the booking people for not losing in 14 WM's.
An outside contender has to be Edge however. He has had some phenomenal WM matches, like the TLC match at WM 2000,and X7,the first money in the bank match, and thte enjoyable hardcore match against Foley.And I'm EXPECTING the Money in the Bank match this year to be great. (I'm blatantly not mentioning his sub-par match against Booker T)
