Pass and Crash...

[Nonstop]

What philosophy do you follow with the "pass and crash" at the HS level?

A couple situations to think about:

1) On a drive in the lane A1 passes to A2. A1 immediately "crashes" into B1 who has a legal guarding position. A2 makes a basket. What if there are one or two steps after the pass before A1 "crashes", rather than immediately?

2) On a drive in the lane A1 passes to A2. A1 immediately "crashes" into B1 who has NOT obtained legal guarding position. A2 makes a basket.

What if players are on the floor? What if they aren't?

When is a no-call appropriate and when not?

I may have opened a can of worms here, but I think this play is a tough "instinctual" call. Meaning, if I don't think through the call now, I may leave myself hanging on the court.

Thanks!
