How the Start/Sit Tool Works

1

Projection Engine

Our algorithm projects each player's expected fantasy points using volume metrics (targets, carries, snap count), matchup quality, game script probability, and recent performance trends weighted over the last 3, 5, and 10 games.

2

Matchup Analysis

Every player is graded against their opponent's defensive ranking at their specific position. We account for pace, defensive scheme, and how teams allocate targets and rushing attempts when trailing or leading.

3

Side-by-Side Verdict

The comparison highlights advantages in projection, floor/ceiling, and matchup quality so you can make confident decisions. We factor in scoring format (PPR, Half-PPR, Standard) to tailor the recommendation to your league.

Key Start/Sit Decision Factors

Matchup Analysis

The single biggest variable week-to-week is the opponent. A wide receiver facing a bottom-5 pass defense has a significantly higher ceiling than one facing a top-5 unit. Look at position-specific defensive rankings, not overall team defense.

Recent Performance Trends

Weight recent games (last 3) more heavily than season-long averages. A player trending up in targets and snap count is more valuable than their season average suggests. Conversely, declining volume is a red flag even for high-ranked players.

Injury & Weather Impact

Monitor practice reports Wednesday through Friday. Players listed as questionable with limited practice participation carry risk. For outdoor games, high wind (15+ mph) suppresses passing, favoring run-heavy game scripts and hurting pass catchers.

Game Script & Vegas Lines

Implied team totals from Vegas are the best predictor of offensive output. Teams with high implied totals (24+) are in favorable spots. Large underdogs tend to pass more in the second half, boosting pass catcher volume but reducing RB value.

Frequently Asked Questions

How do I decide who to start in fantasy football?
The best approach combines multiple factors: projected points based on matchup, recent performance trends (last 3-5 games), target share and snap count, opponent defensive rankings by position, weather conditions for outdoor games, and injury status. Use a side-by-side comparison tool to evaluate these factors for each player in your lineup decision.
What factors matter most for start/sit decisions?
Volume is the most important factor - players with guaranteed touches and targets have higher floors. After volume, consider matchup quality (opponent defensive ranking vs. position), game script (is the team favored or an underdog?), recent performance trends, and red zone opportunity share. For PPR leagues, target volume matters more than rushing volume.
Should I start a player on Thursday Night Football?
There is no inherent disadvantage to starting Thursday Night Football players. The key is evaluating them the same way you would any other player - matchup, volume, and recent performance. The main risk is having less time to react to late-breaking news, so check injury reports early Thursday afternoon before lineups lock.
How do bye weeks affect start/sit decisions?
Bye weeks force you to start backup options from your bench. During bye weeks, prioritize high-floor players over boom-or-bust options to maintain a competitive baseline. Check the waiver wire for streaming options at QB, TE, and DST. Plan ahead by identifying bye week conflicts during your draft to ensure adequate depth.
What is a fantasy football flex play?
The FLEX position in fantasy football allows you to start an additional RB, WR, or TE (depending on league settings). The best flex strategy is to start the player with the highest projected points regardless of position. Consider matchup, volume, and ceiling - in tournaments, a high-ceiling WR in a favorable matchup often makes the best flex play.
