🏀 Best March Madness Upset Picks Today: Second Round Underdog Plays for Saturday (March 21)

C Jackson Cowart is the Senior Publishing Editor at Sportsbook Review, specializing in NFL and NASCAR betting while helping lead the team's coverage of college sports and major events like the Super Bowl and March Madness. In his seven years covering sports betting as a predictive analyst, features writer, and industry reporter, he has stayed true to "process over results" while specifically targeting futures betting and news-driven markets, where he can lean on advanced metrics and an understanding of market psychology to attack value before the number moves. His favorite sportsbook is FanDuel for its clean interface and ease of use, though he finds some of his best value bets at Caesars and bet365, especially for NASCAR. An award-winning writer and editor with a decade of experience in sports media, "C-Jax" has worked with ESPN, Forbes, theScore, and multiple large daily newspapers before joining SBR in 2023. He's a proud graduate of the University of North Carolina, where he covered the Tar Heels' championship run through the 2017 NCAA men's basketball tournament. He's cashed some big tickets over the years — including Lamar Jackson to win MVP (twice) — but he's still haunted by enough second-place slips to wallpaper his home office.
