Mac McClung of the G League's Osceola Magic goes for a three-peat when he takes part in the 2025 NBA All-Star Slam Dunk contest on Saturday at Chase Center in San Francisco. No one has ever won three in a row, but McClung is looking to make history. He can also tie Nate Robinson (2006, 2009 and 2010) for most career Slam Dunk championships. 

The 2025 Slam Dunk contest will be the third and final event on All-Star Saturday Night, which begins at 8 p.m. ET and also includes the Skills Challenge and 3-Point Contest.

McClung is the -175 betting favorite (risk $175 to win $100) in the 2025 Slam Dunk contest odds, followed by Matas Buzelis (+550), Stephon Castle (+600) and Andre Jackson Jr. (+600).

Barner's expertise has been on full display lately as he enters the All-Star break on an 80-52 run on NBA prop picks (+1836)! Over the past five seasons at SportsLine, Mike has crushed sportsbooks with a 470-406 record, returning $2,329 to $100 bettors on against-the-spread NBA picks. Anyone following could have seen HUGE returns!

Now he has analyzed the 2025 Slam Dunk contest from all angles and is delivering his picks for SportsLine. We can tell you that Barner is fading McClung, even though he is one of the favorites. Barner doesn't like that McClung will be facing a difficult process in determining a winner. "Given how flukey that process can be, I can't pay these odds for McClung to win, regardless of how impressive he has been previously," Barner told SportsLine.

Instead, Barner's Slam Dunk winner is a longshot he describes as having "the potential to provide some exciting, high-flying dunks." You ABSOLUTELY need to see who it is before locking in any picks of your own.
