What's known is that Roberts receives input from Andrew Friedman's analytically inclined front office before games on the situations he might encounter and how he should respond. Less certain is the degree to which Roberts is expected to follow the blueprint.
The point is that Roberts might not be entirely responsible for the choices he has made in this World Series, which the Dodgers trail two games to none. Maybe Friedman, general manager Farhan Zaidi and the army of number crunchers employed by the Dodgers are equally at fault.
Except the details have become insignificant. Regardless of how the decisions are being made, they're not working.
