So, under NCAA rules, if the receiver is already going to the ground on his own as here where he basically tripped himself, and then he's contacted by the defender in the process of going to the ground, where does that fit in the rule?
I think people are mixing up NCAA ARs with rules. ARs are not rules, they are specific interpretations of specific plays that attempt to illustrate certain aspects of the rules. They are not exhaustive, so statements like "Any receiver going to the ground on his in the process of making a catch must maintain control of the ball when he hits the ground", which is in AR 7-3-6-XII is NOT a rule, and does not apply beyond the confines of the statement it is made in.
In other words, this statement is true for the play described, it does NOT say that the "on his own" part makes the statement true, and absent that clause, the statement is no longer true.
