This fight is not for the casual boxing fan.

The casuals will say this is "boring." The purists will appreciate the mastery of both fighters. The casuals want fireworks, while the purists appreciate the respect both fighters have shown each other. On one side, we have the undefeated, fully unified lightweight champion Haney (29-0, 15 KOs), and on the other side, we have legendary Ukrainian southpaw Lomachenko (17-2, 11 KOs).

Ignore any talk that Loma is too old. At 35, he is a year younger than Floyd Mayweather Jr. was when he faced Canelo Alvarez, so age is no excuse.

There is a good reason the 24-year-old Haney is a slight favorite (-270 on DraftKings). "The Dream" is taller, stronger and the most versatile opponent Loma has ever faced. And don't get us wrong: Haney's ring IQ, elite defense and jab will make it difficult for the Ukrainian.

We've seen Loma struggle against a lesser fighter with similar height/weight measurements in Jamaine Ortiz. Because of this, Loma understands why he's the underdog.

Still, this is also Haney's most challenging opponent. Lomachenko is no George Kambosos Jr. He is a three-division champion and two-time Olympic gold medalist. Haney very well may be the future of boxing; will that be in the lightweight division? It's well-known that he'll move up to 140 pounds soon. Will he have enough power in his punches Saturday?

Conventional wisdom says Haney will send Lomachenko into retirement; however, this is a legacy fight, and I expect Loma to shock the boxing world. He will be the first man to defeat Haney in a professional contest and become the new WBA, WBC, WBO and IBF lightweight champion.

Prediction: Lomachenko by unanimous decision
