guarding the

[ysong]

Need help for another question.

From a note in NFHS 10-6-3:

"It is assumed the guard may shift to maintain his/her position in the path of the dribbler, provided he/she does not charge into the dribbler nor otherwise cause
contact, as outlined in 10-6-2."

"The guard may not cause contact by moving under or in front of a passer or thrower after he or she is in the air with both feet off the floor."

in this note, what is noticeably missing in the underlined part is "a dribbler". So I wonder:

when facing a guard who establishes his legal guarding position, a dribbler jumps to the side of the defender in an attempt to dribble around him. but in the same time, the defender maitains his guarding position and moves laterally into the path of the dribbler, after the dribbler initiates his jump. when the dribbler falls on the defender's front torso, which player is responsible for the contact?

also, when the dribbler senses that the contact is immiment, he throws the ball away before he lands on the defender, now who should be called foul?

Thanks.
