The Action Network: NASCAR odds, picks, predictions for Kansas

Kansas Speedway hosts the second straight 1.5-mile race for the NASCAR Cup Series. Sunday's AdventHealth 400 (3 p.m. ET, FS1, MRN Radio, SiriusXM NASCAR Radio) hopes to live up to last year's excitement after producing the closest finish in Cup Series history. Even if it doesn't, Kansas is an exciting track with multiple grooves of racing, where a premium is placed on speed. What better way to gauge speed than my FLAGS data from the practice session, which shows one of the top drivers in the series and in practice is undervalued in the betting market.

NASCAR Odds, Best Bet Pick for Kansas

*Odds as of Sunday morning Kyle Larson was easily the No. 1 driver in my practice FLAGS metric, which compares every driver to each other on a lap-by-lap basis (while removing any outlying laps). Larson's 94.1% FLAGS metric ranked first. In the second tier, just behind him, was his teammate William Byron, with an 85% FLAGS rating. Byron has also been a stellar performer overall, currently leading the points standings, and has two top-three finishes at Kansas in the last four races, including a runner-up result in the series' most recent visit to the track. At Las Vegas Motor Speedway, which is arguably the best comparison to Kansas, Byron took home a fourth-place finish earlier this year, when he ranked first in average running position and second in green flag speed. My model gives Byron a 32.4% chance for a top-three finish, which is closer to +210 as fair odds.
