First of all, the Dutch FA wants kick-ins to take the place of throw-ins. They also want the introduction of sin bins, a proposal that the International Football Association Board (IFAB) has already discussed. They also want self-passes from free kicks and flying replacements, which would effectively let a manager make as many substitutions as they would like throughout a match.
The most significant rule change recommendation comes in their final proposal, which calls for two 30-minute halves instead of the normal 45. They have also proposed for the stop clock to be paused every time there is a stoppage in the game so as to have a guaranteed 60 minutes of action.
