When you think about it, Savage was basically involved in the biggest or 2nd biggest angle of the majority of the first 10 manias
2 - Pretty big feud w/ Steele over IC belt
3 - Huge feud w/ Steamboat leading to greatest WM match ever (in most opinions)
4 - Wins 4 matches to earn heavyweight title - nuff said
5 - Mega Powers explode, on the losing end of match, but the biggest storyline at the time
6 - Mixed tag novelty act, but again one of the few feuds going into mania
7 - Several month long feud with Warrior pays off in great Career ending match/match of night
8 - Wins 2nd heavyweight title beating legendary Ric Flair after another great feud
10 - As someone mentioned earlier, turned a not so interesting story with Crush into a pretty decent feud
People say Hogan made Wrestlemania, but perhaps it was Savage
