Stop using past performance to evaluate fantasy players. Start using the future. Each week, numberFire will provide updated projections for future fantasy points through Week 17. To go with the numbers, Field Yates will provide analysis on what the numbers reveal. Fantasy players have a new resource to evaluate trades and roster moves: The Fantasy Future Rankings.

Building a fantasy lineup each week is a careful exercise in evaluating past performance while projecting future production.

In the case of Rams rookie running back Zac Stacy, a fast riser in numberFire's TPS metric (which measures a player's value for the rest of the season relative to the average fantasy starter), there isn't much production to speak of: 15 total fantasy points this year.

At least, there's not much to speak of yet.
