Before setting any NASCAR DFS lineups for Sunday's 2021 GEICO 500 at Talladega Superspeedway, you NEED to see what Mike McClure has to say. McClure is a predictive data engineer and DFS pro with nearly $2 million in career winnings.

McClure dominated NASCAR DFS at the 2020 Daytona 500, turning a 4x ROI after rostering four of the top seven drivers. He then crushed the 2020 Real Heroes 400, with his top three picks -- Denny Hamlin, Erik Jones and Martin Truex Jr. -- all finishing in the top eight. He also had Truex Jr. No. 1 in his DraftKings value rankings for his huge win at Martinsville and then ranked Kevin Harvick No. 1 for his win in Indianapolis.

Last week, McClure had Alex Bowman listed as his top NASCAR DFS pick and Bowman went on to capture the win at Richmond. His model has also nailed seven of the top 10 finishers in four of the last six races. Anybody who has followed his picks has seen HUGE returns.

Now, he's turned his attention to the 2021 GEICO 500 on Sunday and is revealing his top NASCAR DFS picks and driver pool.

For NASCAR at Talladega, we can tell you McClure is high on Harrison Burton at $3,000 on FanDuel and $7,900 on DraftKings. Part of McClure's optimal NASCAR DFS strategy includes rostering Ricky Stenhouse Jr. at $11,000 on FanDuel and $8,500 on DraftKings. Stenhouse won at Talladega in 2017 and has five top-five finishes there in his last nine cup starts.

McClure is also targeting an undervalued driver set to return HUGE value! He's in prime position to make a run at the checkered flag and comes at a price that won't break the bank. This pick could be the difference between cashing HUGE in your tournaments and cash games or going home with nothing.

So what are the top NASCAR DFS picks for Sunday's 2021 GEICO 500? And which value driver is a must-roster? ... Join SportsLine right now to see DFS millionaire Mike McClure's top picks and complete driver pool and strategy, and cash big on NASCAR at Talladega!
