Throw-in ... Step Over Line

[Richard Ogg]

We've all agreed that on a throw-in, if the inbounder steps over the line it is a violation.

Yesterday I attended the rules interpretation meeting for Northern California, and now I'm not so sure. At that meeting we discussed players who never quite get OOB before throwing the ball. This will be called a violation. However, the only requirement for a legit throw-in is the player be officially OOB. That means if they step on the line, they are good-to-go.

Now I'm thinking about the inbounder that steps over the line, but their other foot is still on the floor OOB. I suspect there is something about breaking the plane, but will have to look in the book later. Thoughts?
