Simultaneous basket interference by both teams

[TimTaylor]

JV boys game. A1 shoots from about 14' out, shot is slightly short and the ball bounces up off the front of the rim, hits the backboard, then goes in. Now the fun part - while the ball is in the cylinder, but before it drops through the rim, both A3 & B3 grab a handfull of net (yes it caused the rim to move). The decision we made on the spot was to wave off the basket, then go with the possession arrow for the subsequent spot inbound.

Any thoughts on this? I thought about it on the drive home and don't see how we could have done anything else......did we miss anything?
