Even Shakur Stevenson -- one of the most talented boxers in the world -- is admittedly surprised he's a big favorite over undefeated opponent, Oscar Valdez, straight-up telling TMZ Sports he doesn't get it.
"I actually don't understand it. I'm thinking like the odds are gonna be closer. I was willing to go put my whole fight check up for this fight, but you gotta give him the respect he deserves ... but I don't think the fans are," Stevenson says.
"Well, not the fans but the betting odds and the people and all that, I don't think they giving him a fair shake which I understand 'cause it's me but at the end of the day, I don't understand it either."
But, don't mistake Shakur's honesty for a lack of confidence in his ability ... he's just keeping it a buck, saying what educated fans know -- Valdez has hands.
FYI, 31-year-old Valdez, who has been working with Canelo Alvarez, has never lost a professional fight ... he's 30-0 with 23 knockouts.
Stevenson is younger ... just 24 years old, and is also undefeated at 24-0 with 9 KO's.
Despite the career accolades, Oscar is a sizeable underdog ... especially for a champion. In fact, many sportsbooks require you to lay down (-)$800 simply to win $100. Believe Valdez will win (like Canelo)? You'll only have to risk $100 to win (+)$500.
Obviously, Shakur's not overlooking Valdez ... and when we asked him if it was the toughest fight of his career, Stevenson was inclined to agree.
"On paper. On paper when they look at the records and what Valdez has done in the sport of boxing already, it looks like it's the hardest fight of my career but we never know until we get into the ring."
"Stylistically, it might be one of the easiest fights or it may be the hardest fight at the end of the day. You never know until you get in the ring."
Barring something wacky, one of the fighters -- a combined 54-0 -- is taking their first L on April 30.
