You actually got me thinking, does anyone have a current flow chart for BBW?
The best way I've found to officiate the BBW rule is the block has to be "IN-IN" to be able to block from the side by unrestricted players. The BLOCK has to be IN the zone and the BALL has to be IN the zone for unrestricted players to be able to legally block low from the side. If you have IN-OUT, it has to be 10-2 or it's a foul. Thinking "IN-IN" is an easy way to process the rule in the time you need to make the decision.
If you're unrestricted, you ALWAYS have to be 10-2, and you can't crack back or peel back.
