I may have been calling a play wrong. A1 dribbling quickly from BC to FC, B1 establishes LGP about 10 feet ahead of A1, two feet from the sideline. A1 is able to pass B1 (both running by now), but in doing so, is forced OOB by slight contact by B1. I have always called a foul on B1. But Rule 4-7-2c states, in part “If there is less than 3 feet of space, the dribbler has the greater responsibility for the contact”. So of course we must determine what “greater responsibility” means. In my case above, does it mean no foul, and an OOB violation on A1?
Here is a link to a similar discussion, but it involved a "hip check", not slight contact.
