Violent collision, equal opportunity to the ball?

[assignmentmaker]

I didn't see this in today's Kansas/OSU game, but a son called to ask me for a ruling.

The ball was being passed a long ways down the floor from A1 to A2, who was beyond B1. The pass was short. B2 backed up to intercept it as A2 sped up the floor towards the ball. For argument's sake, say that, as they collided, each was able to touch the ball.

I am interested from a high school rules perspective. I have in mind, in particular, 4.27.2, which says " . . . Contact which occurs unintentionally in an effort by an opponent to reach a loose ball, or contact which may result when opponents are in equally favorable positions to perform normal defensive or offensive movements, should not be considered illegal, even though the contact may be severe . . ."

I understand that there is team control while a live ball is being passed, but the 'or' phrase in the text above, does not state whether or not the condition of 'loose ball' carries over. If it doesn't, and they had equal opportunity to catch the pass . . .
