charge/block rule

[Hawks Coach]

The other thing to remember about charging is that the rule may be short, but understanding it requires understanding a number of related concepts, such as legal guarding position, rules governing contact in general, verticality, etc. So a number of rules come into play on this, as with many other calls in basketball.

The book is hard to understand when you go looking for one rule to explain something like block-charge, because it isn't as simple as one rule.
