OK newbies - try this one. A1 in backcourt. A1 attempts pass to A2 who is in frontcourt but the pass hits an official in the frontcourt and bounces back to A1 who touches it in the backcourt. What's the call, if anything?
BTW - I've only seen this happen once in 21 years of officiating, but of course, it will happen in your next game
