My, oh my.....more paralysis by analysis.
1) It is the head coach's responsibility to ensure that he has the proper number of players on the court. It is
NOT the responsibility of the officials and it
NEVER has been the responsibility of the officials.
2) Yes, we as officials try to ensure that the proper number of players are on the court. However, sometimes sh!t happens. It happened in an NBE game t'other week and all three officials missed it. If it does happen, just damn-well
deal with it instead of going through these stoopid, non-sensical blame games. We've got very explicit rules in place to deal with these situations. When in doubt, it's not a bad idea to try using those rules.
Lah me.....
