Before you set your daily fantasy sports lineup on DraftKings for UFC 224 at Jeunesse Arena in Rio de Janeiro on Saturday, you need to hear what Mike McClure has to say. McClure is a predictive data engineer and DFS pro with more than $1 million in career winnings.

He has crushed his DFS selections in multiple sports recently, producing tournament rosters that have cashed huge in NFL, NBA, NASCAR, golf and NHL. He's been all over his recent UFC picks as well.

For UFC Fight Night Atlantic City in April, McClure locked Kevin Lee in his DraftKings lineup at just $8,400. The result: Lee scored big on the main card with a technical knockout of Edson Barboza.

Anybody who had Lee in their lineups was well on their way to a profitable MMA DFS night.

Now, he has set his sights on Rio and revealed his optimal DFS lineup for UFC 224 on Saturday. He's sharing that lineup only over at SportsLine.

One value fighter McClure absolutely loves for UFC 224: Vitor Belfort at $7,300 on DraftKings. "Belfort is the true underdog pick," McClure told SportsLine. "You need at least one underdog based on the DraftKings pricing. Belfort is a high-variance fighter who has seen over 70 percent of his fights end (win or lose) in the first round. This kind of variance is what we want in a cheap fighter."

Getting a discount on a fighter like Belfort will leave plenty of room for a high-end option like Markus Perez, who is $9,200 for his fight against James Bochnovic.

Perez is as much as a -325 (wager $325 to win $100) favorite, and McClure loves his chances for a first-round knockout. Lock him in your lineup and look for a huge return on DraftKings.

McClure is also targeting a "must-play" fighter who is primed for a dominant performance. Picks like these could be the difference between cashing huge in DFS or going home with nothing.
