Block, charge, no call travel?

ART. 4

Guarding an opponent with the ball or a stationary opponent *without the ball:

a. No time or distance is required to obtain an initial legal position.

b. If the opponent with the ball is airborne, the guard must have obtained legal position before the opponent left the floor.

This is all in response to Nevadaref's statement that since A1 landed prior to contact, it doesn't matter when B1 gained position with regard to A1 going airborne.
