It will depend on their age. Are you coaching a younger age group where players are rotated through all positions?  

I am coaching beginners in year 3-4.  I use a half and half approach (but it would also work if you rotated each quarter). This is how I do it:

        1st - 2nd half

1. GS - WA
2. GA - off
3. WA - GS
4. C - off
5. WD - GK
6. GD - off
7. GK - WD
8. off - C
9. off - GA
10. off - GD

In theory each player will get a fair run, and with the younger players, there is not too much confusion swapping positions because they are moving to a similar position rather than a completely different position.

Each week I then move the players around so that over the season they play each of the 1-10.  It should also mean equal time on and off the court for all players over the season.

For older players it will depend on the positions they play, but similar principles would work.

Hope this helps!
