There is a big difference between "focused on statistics" and a valid statistical approach. Quoting ERA, Wins, RBIs, and even advanced metrics like WAR/FIP/VORP is totally different than validating methods through regression, machine learning, and the like. Everyone is happy to point at "stats." Almost nobody wants to hear about confidence intervals.
