Who has been the most exiting fighter of this decade?

[XaduBoxer]

PAC ?? He started to give significant exciting fights on world stage since 2001 when he annihilated the then avoided IBF super bantam champ Ledwaba and until today PAC is still dishing out exciting fights one after the other with more expected to come in the future... PAC vs. Hatton, how exciting this fight would be??

BTW, just realized you're asking for "most exiting fighter", do you mean those retiring fighter??
