Why It Matters: Even if you are solely a mixed martial arts (MMA) fan. Scratch that. Even if you never once cared about combat sports in your life, there is something special about any event being deemed the most important in the last 100 years. For boxing enthusiasts, this fight is essentially a fantasy playing out right in front of their very eyes. Mayweather vs Pacquiao has brought intrigue for nearly five years, and they will finally settle the score tonight. Whether or not you are a fan, this fight will break all records, and will ultimately be remembered for years to come. This is truly a once in a lifetime moment for sports fans, so sit back, relax, and enjoy what hopefully will be an epic battle between the two greatest boxers of our generation, and potentially of all time.

What's Hot: You already know about the highly anticipated main event, but were you aware of the two televised bouts prior to the historic showdown? As if Mayweather vs Pacquiao alone was not enough to whet the appetites of combat sports fans, pugilistic enthusiasts will also be treated to two more title fights when WBO featherweight champion Vasyl Lomachenko puts his title on the line against the dangerous Gamalier Rodriguez. The second bout will feature WBC super bantamweight title holder Leo Santa Cruz, as he challenges Jose Cayetano in what should be a thrilling affair.

What's Not: To be frank, it is absolutely ludicrous that this PPV is so expensive. Ultimately, fight fans who prefer watching events alone will either be forced to dish out a cool Benjamin or head over to a local bar to catch the action. Sure, it is the biggest fight of the century, but is the $100 price point really necessary? Seems like overkill to me, but it sure won't stop millions of people from clicking "purchase" later on this evening.
