Record should matter, but not dominate
Wins are part of any league ranking formula because standings drive the season. But wins alone are a weak summary of team quality when schedule luck is extreme.

What belongs in a fantasy football power rankings formula
The point of a power rankings formula is not to restate standings with nicer typography. It should explain team strength better than the standings page does.
Points scored and head-to-head context add signal
Raw scoring and head-to-head outcomes together tell you more than standings do by themselves. Teams that consistently score well but sit below their record deserve a closer look.
Lineup efficiency separates roster strength from management
Two managers can own similar players and produce very different results depending on sit-start decisions. That is why an optimal-lineup view belongs in a useful power rankings formula.
Forward-looking strength matters late in the year
As the season develops, a good rankings formula should care about where a team is heading, not only what already happened in September.
