With this particular team, the time should be spent on those aspects that have been preventing us from winning. Since our passing efficiency has been down this year, due mainly to turnovers, that should be our prime concern in practice. There should be enough time left over to spend on improving the run game. Your point is valid here, though, since truly improving our run game probably means healing the injured and bringing in new personnel. However, small changes can always be made involving blocking schemes and play selection, which would not involve any great time expenditure.
