You knew this name was coming, and it's not just because he wrestled a bear once. Khabib Nurmagomedov is the hottest name in the UFC lightweight division right now. He doesn't have the name recognition of a Diaz, Henderson, Melendez, or Gomi, but he's undefeated, and wrecking everyone put in his path. No one seems to want to fight the guy, and can you blame them? The Dagestani-born Russian has won all six of his UFC bouts over the likes of Rafael dos Anjos, Pat Healy, and Gleison Tibeau, and is 22-0 overall in his career. He also holds the record for most takedowns in a fight in the UFC, and could give Anthony Pettis some serious trouble.
