Yahoo's single-game offering has a roster construction of one "Superstar" that scores at a 1.5 multiplier, while the remaining four FLEX roster spots accumulate points at the normal rate. This is half-point PPR scoring and the "Superstar" salary does not change from the Utility. All scoring and rules can be found here.
It is vital to remember that single-game slates are not simply a “max salary, play as many big names as possible, and submit” format, especially in larger tournament fields. We need to identify players who can be pieces in their offense’s success, whether in the lead or trailing, as well as the players who could be focal points in a neutral game script.
