#30 ‘Mania without a singles matches
WrestleMania 2000, the 16th annual WWE WrestleMania event has the distinction of being the only WrestleMania to not have a straight up one-on-one single’s wrestling match.
Yes, The Kat vs. Terri was a singles match on paper but the match was an overbooked fiasco. The Fabulous Moolah and Mae Young were at ringside during the match and got heavily involved in the match while Val Venis was the special guest referee.
#29 WrestleMania without a tag-team match
WrestleMania 21 has the unique distinction of being the only WrestleMania to not feature a tag-team bout on the card.
The card featured mostly singles matches except for the then-traditional Money In The Bank Ladder match and a Battle Royal. The show was headlined by Triple H and Batista but sadly for fans of Tag-Team wrestling, WWE found a spot for Big Show vs. Akebono but not for the WWE Tag-Team Championships to be defended at the very least.
