Rain washed out qualifying on Saturday and then pushed the 2018 Brickyard 400 to Monday afternoon at 2 p.m. ET at Indianapolis Motor Speedway. There's still plenty on the line, however, as drivers get set for the final run of the regular season with positioning for the 2018 NASCAR playoffs up for grabs. The 2018 Brickyard 400 odds have been on the move as rain has shuffled the schedule around. Kyle Buch is the favorite in the latest 2018 NASCAR at Indianapolis odds at 5-2, following closely by Kevin Harvick at 3-1 and Martin Truex Jr. at 7-2. Before you make your NASCAR picks on the Big Machine Vodka 400 at the Brickyard, be sure to check out what former Vegas bookmaker and NASCAR handicapper Micah Roberts has to say.

Roberts has nailed two of the last five race winners. Three weeks ago, he said Harvick would dominate at Michigan, and he won with ease. Before that, he was all over Busch at Pocono, pointing to not only his 26 career starts at the track, but also his motivation to win after a late bump from Harvick the week before. The result: Busch rallied from 28th for the checkered flag.

Those are just the latest examples in a string of winners he has picked. Earlier this season, he was all-in on Harvick at the Folds of Honor QuikTrip 500 despite two other drivers having the same field-leading odds. The result: Harvick dominated, leading for 181 of 325 laps and cruising to victory by 2.69 seconds.

At the Food City 500, Roberts said Busch "owned" Bristol and would come away with the win -- he rallied to finish .63 seconds ahead of Larson for the checkered flag.

In the 2017 playoffs, Roberts picked nine of 10 winners. That was no fluke: In 2016, he told readers to back Denny Hamlin at 15-1 in the Daytona 500. The result: Hamlin edged Martin Truex for the checkered flag. Roberts also nailed Hamlin at 40-1 to win at Watkins Glen later that year.

Now, he has analyzed NASCAR at Indianapolis 2018 from every possible angle and locked in his picks. You can see his entire projected leaderboard at SportsLine.

We can tell you he's not picking Busch, despite two wins in the last three years at Indianapolis. Roberts says there are far better values in the loaded Brickyard 400 field. 

One long shot Roberts says has a strong chance to finish in the top five at the 2018 Brickyard 400 on Monday afternoon: Jimmie Johnson at 80-1. 

"He has six top-five finishes in 16 Brickyard starts, and four of them are wins," Roberts told SportsLine. "One more win and he'll tie Jeff Gordon for the most in track history. He has never gone this long into a season without a win. The main reason he stands out is that Hendrick Motorsports and Chevrolet have been faster. They showed their strength in the last Pocono race with two cars in the top six. This is the lottery ticket of the week that can actually cash."

But for the win, Roberts is banking on a sleeper who has not won this season. Vegas isn't giving him enough credit, but "it's his time," Roberts said. Also, Suarez isn't the only huge longshot Roberts has making a strong run at the title. Anyone who backs this driver could bring in a life-changing haul.
