OOB Throw In - Step on the line

[doubleringer]

I had this conversation with one of my high school partners when we first became a crew. I told him to think of a gym where they don't have lines, just the oob painted a different color than the court. When would you call the violation there? That helped me visualize early on that it is not the inside edge of the line, but the edge of the line nearest the court.
