I'm having a hard time understanding some of the Backcourt Violation examples.
-Ball bounces in backcourt, A1 jumps from frontcourt grabs the ball in the air and throws it back to the front court. Violation?
-Team A throw-in, A1 jumps from front court grabs the ball in the air then lands in the backcourt. Violation?

Is there a way to understand some of the weird backcourt violations that can happen or what looks to be a backcourt violation but is not?

Thanks
