Since 2008, D.S. Williamson has written about sports and sports handicapping. His philosophy is value-based, meaning stats and other handicapping factors are only worth something in comparison to wagering odds. He believes money management and making value-based wagers is the single more important factor that distinguishes successful sports bettors from non-successful sports bettors.
