The NASCAR Cup Series continues at the iconic Talladega Superspeedway on Sunday. The green flag drops on the 2021 GEICO 500 at 2 p.m. ET, when Joe Gibbs Racing drivers could have a distinct advantage with all four of its cars starting inside the top 10. Denny Hamlin has been awarded the pole in the 2021 GEICO 500 starting lineup using NASCAR's competition-based formula, but will a lack of passing upside diminish the NASCAR DFS value of the last driver to win at Talladega?

With Martin Truex Jr. starting third, Christopher Bell starting sixth and Kyle Busch starting ninth, using Gibbs drivers in NASCAR DFS stacks might be a winning strategy with drafting and blocking playing such an integral part of superspeedway racing. But if you're going to load big names into your 2021 GEICO 500 DFS lineups, you'll have to find more affordable options deeper in the NASCAR DFS driver pool. Before finalizing your NASCAR DFS picks for the 2021 GEICO 500 on sites like DraftKings and FanDuel, be sure to check out the optimal NASCAR at Talladega DFS strategy and advice from SportsLine's Mike McClure.

McClure has won almost $2 million in his career as a daily Fantasy pro, and his NASCAR DFS driver pool, projections and advice can help you score a big win on Sunday. 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. at No. 1 in his DraftKings value rankings for his win at Martinsville and then had Kevin Harvick at No. 1 for his win at Indianapolis.

Last week, McClure listed Alex Bowman as his top NASCAR DFS pick and Bowman went on to win at Richmond. His model has also nailed at least 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 Sunday's 2021 GEICO. He's only sharing his picks and NASCAR DFS driver pool here.

Top 2021 GEICO 500 NASCAR DFS picks

For NASCAR at Talladega, McClure is high on Harrison Burton at $3,000 on FanDuel and $7,900 on DraftKings. The 20-year-old is coming off a rookie season in the Xfinity Series in which he piled up four wins and finished eighth in the standings. He's had five top-10s in seven starts already this year too.

Now, he's scheduled to make his NASCAR Cup Series debut, where he'll have a spot start driving the No. 96 Toyota for Gaunt Brothers Racing. Burton will start from the back of the pack as a non-points qualifier, which gives the skilled youngster plenty of passing upside for daily Fantasy NASCAR lineups this week.

Part of McClure's optimal NASCAR DFS strategy includes rostering Ricky Stenhouse Jr. at $11,000 on FanDuel and $8,500 on DraftKings. The 33-year-old is pretty well established as a superspeedway specialist at this point in his career. Both of his NASCAR Cup Series victories came on superspeedways and eight of his 19 career top-five finishes have been in restrictor-plate races despite only running on those tracks four times per season.

Stenhouse won the 2017 GEICO 500 and then was the runner-up to Ryan Blaney in the 2020 GEICO 500. That gives him three top-five finishes in his last four spring starts at Talladega and makes him a driver with tremendous upside in a race where it can be hard to find reliable options.

How to set 2021 GEICO 500 NASCAR DFS lineups

McClure is also targeting an undervalued driver set to return plenty of 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 NASCAR DFS tournaments and cash games or going home with nothing. You can see every pick here.
