I voted for the Hardy Boyz. They were my favorite team growing up. I really liked their feuds with the Dudley Boys and E&C.
I don't get why some teams are on this poll though.
I mean HHH and Shawn Michaels? DX were a great faction, but HHH and HBK weren't a prominent team when you think about tag teams. Same goes for Kane and Undertaker and Miz and Big Show.
You could have picked better teams, like the New Age Outlaws or even teams like Miz and Morrison, The Colons (Carlito and Primo) and Duce and Domino I think.
London and Kendrick might be the most forgotten team of this era... They were very exciting though, so I don't know why everyone spaces on them.
