My Hypothesis—DoubleA

  1. Knee injuries in football
  2. Knee injuries and artificial turf
  3. the effect that artificial turf has on knee injuries in the NFL
  4. Playing on grass instead of artificial turf fields will reduce the amount of knee injuries in the NFL
  5. Eliminating turf fields would reduce the amount of knee injuries suffered by NFL players in an NFL game
  6. Eliminating artificial turf fields with real grass fields would decrease the total amount of knee injuries in an NFL season
