At first, I thought the original post was about games at camps for officials...but then read it and it looks like it refers to summer league games.
A few thoughts...
1) The organization I call for during the summer only uses officials with a couple of years experience (unless it is an emergency). You still get someone who doesn't care and someone who has repeated their first year a few times (aint learned nothing...if you know what I mean) but the odds are smaller. Maybe you need to be more selective.
2) Even when working with a "bad partner" you can find things to improve your game...and it happens during the regular season as well. I always remind myself that I am the only one that can impact my feelings and has any control over how I handle my responsiblities. Make sure there is at least one official on the floor giving it their all. Do your best...get in...get done...get out.
3) If you know your partner is passing on an OOB call on his/her line or on contact that obviously impacts the shot attempt...who is watching your area?
