defender putting offense in danger

[SC Official]

The higher you go, the expectation is that you will have a block or a no-call when a defender trying to take a charge is halfway to the ground before he gets touched. The book-based argument is that the defender is violating verticality, which is very controversial on this forum.

There is a difference between bracing for contact, which the rules allow, and what I described above. Call charges on these types of plays and you'll be whacking a lot of coaches and getting calls from your assigner.
