Players thought 2 shots..so did ref

[BillyMac]

This (below) is high school, not college, and I'm not even sure that it matches the situation perfectly, but for the good of the cause, a reminder for all:

8.6.1 SITUATION: A1 is about to attempt the first of a one-and-one free-throw
situation. The administering official steps in and erroneously informs players that
two shots will be taken. A1's first attempt is unsuccessful. The missed shot is
rebounded by: (a) B1, with all other players motionless in anticipation of another
throw; (b) A2, with all other players motionless in anticipation of another throw;
or (c) B2, with several players from both teams attempting to secure the rebound.
The officials recognize their error at this point. RULING: In (a) and (b), the official's
error clearly put one team at a disadvantage (players stood motionless and
didn't attempt to rebound). Play should be whistled dead immediately and
resumed using the alternating-possession procedure. In (c), both teams made an
attempt to rebound despite the official's error and had an equal opportunity to
gain possession of the rebound. Play should continue. (2-3)
