Tenacity

Both Pacquiao and Rios have shown fierce heart throughout their careers: Getting up when they fall, taking a win-at-all-costs approach and never surrendering seems part of their DNA, which is what makes this fight so attractive. Both seek to put on the best possible show every time out, and each fighter figures to be motivated to score a convincing victory after absorbing a loss in his most recent bout.

Advantage: Even
