"If Our QB Stays Healthy..." Calculator
Every NFL fan has asked: "What if our star player stays healthy all season?" Now you can find out. Toggle key players as healthy or injured, adjust position importance weights, and see real-time impact on win totals, point spreads, and playoff odds. Understand exactly how valuable your quarterback, running back, or defensive star really is to your team's championship hopes.
How to Calculate Injury Impact
- 1. Select your NFL team from the dropdown to see their key players and current projected win total
- 2. Toggle players between healthy (green) and injured (red) to simulate different scenarios
- 3. Adjust position weights with sliders to reflect how important each position is to your team's scheme
- 4. View instant results - win delta, spread shifts, and playoff probability changes based on player availability
Pro Tip: Star quarterbacks typically have 2.5-4 win impact. Elite pass rushers and left tackles can swing 1.5-2.5 wins. Try different combinations to see which position groups matter most for your team's success.

Position Importance Weights
Adjust these sliders to reflect how important each position is in your team's scheme. Higher values increase that position's impact on wins, spreads, and playoff odds.
Key Players Health Status
Common "What If" Scenarios
Quarterback goes down for the season
The most impactful injury in football. Elite QBs like Patrick Mahomes, Josh Allen, or Lamar Jackson typically account for 3-4 additional wins. Losing your franchise quarterback usually means a 2.5-4 win drop, 7-10 point spread shift, and 25-40% decrease in playoff probability. Backup quality matters significantly - a capable backup might only cost 1.5-2 wins.
Star pass rusher out for playoffs
Elite edge rushers like Micah Parsons, Nick Bosa, or T.J. Watt can be worth 1.5-2.5 wins over a season. Their absence forces defenses to change schemes, reduces pressure rates by 20-30%, and allows opposing offenses to focus on other matchups. Impact is especially severe in the playoffs against elite quarterback play.
Multiple offensive weapons return from injury
When a team gets back multiple key offensive players (WR1, RB1, elite TE), the cumulative impact can be massive. Each star weapon is worth 0.8-1.5 wins individually, but together they create matchup nightmares that multiply effectiveness. A healthy offensive core can shift spreads by 5-8 points and boost playoff odds by 15-25%.
Understanding Impact Metrics
Win Total Delta
Represents how many additional or fewer wins a team can expect over a full season based on player availability. Calculated using a combination of player WAR (Wins Above Replacement), position value, and team scheme fit. A +3.0 win delta means the team is projected to win 3 more games than baseline with the current healthy roster.
Spread Shift
Shows how betting point spreads change based on player health. Sportsbooks typically adjust spreads by 1.5-2.5 points per win of player value. A -7.0 spread shift means the team went from being 3-point favorites to 4-point underdogs. This reflects real-world betting market reactions to injury news.
Playoff Odds Change
Calculates the percentage point change in playoff probability based on projected win total shifts and remaining schedule strength. Roughly follows this pattern: Each additional projected win adds 8-12% playoff probability for teams near the bubble (7-10 win range), but has diminishing returns for already elite teams (13+ wins) or eliminated teams (<5 wins).
