I am pretty sure that the chains were not created as a design constraint. There is nothing you can really do to avoid hitting the chains. At both regionals I attended, NJ and long island, the balls seemed to not bounce out. Occasionally, one or two would during big barrages and close matches, so it meant controversy. I watched VCU and the balls could NOT stay in the hoop. That was a chaining mistake. The chains were either too close together or too loose/tight.
