2019 Digital Ally 400: Optimal DraftKings lineups from a NASCAR insider

Before setting your NASCAR DFS lineups on DraftKings for Saturday's 2019 Digital Ally 400 at Kansas Speedway, you'll want to see what NASCAR insider Matthew Mayer has to say. Mayer is a NASCAR writer for CBS Sports who regularly interviews the biggest names in the sport. He goes straight to the source to get a feel for who to back and who to fade each week.

His approach has led to some HUGE results in NASCAR DFS this year. He was all over Martin Truex Jr.'s win at Dover and stacked his DFS lineup around him for a big cash. He also called Jimmie Johnson's win at The Clash and finished in the top 5 percent of lineups for the Daytona 500, in addition to winning big on his NASCAR at Texas DFS lineups and calling Kyle Busch's win at Phoenix. Now he's turned his attention to Saturday night's NASCAR at Kansas slate and locked in his optimal lineup.

One driver Mayer is high on at Kansas: Kurt Busch at $9,600 on DraftKings. "I'm spending big on Kurt Busch as a veteran who has never won at the track," Mayer said. "They're already surprised with how the package is racing here, so have to rely on the veteran to work his way through the field and secure a top 10."

Mayer is also targeting an overlooked driver who has a strong track record at Kansas. 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 is the optimal NASCAR DFS tournament lineup for the Digital Ally 400? And which value driver is a must-roster? ... Join SportsLine right now to see NASCAR insider Matthew Mayer's complete optimal tournament lineups for DraftKings, and cash big on NASCAR at Kansas!
