Here is a substional rule that I have not seen used by coaches or players since I have been officiating in the 2000’s and this is for all levels, Travel, AAU, MBR. MAC middle school thru to college.
Knowledge and using this rule can be very benefical toi both teams.
Rule 3.Section 3 Article 1 e states…”A captain may request a defensive matchup if three or more substitutes from the same team enter during an opportunity to substitute”.
Have you ever seen a team captain do this when this happens. In working over 4000 games in the 2000’s I have never had a captain request a lineup in this situation.
To make sure that defensive assignments are correct, capatins should request a lineup to make sure every player knows who they are guarding if they are playing man to man defense.
