RTP enforcement

[Rich]

I am going to post a few plays to get us away from arguing with the coach in the other thread and talking football.

This is pretty basic, but I just wanted to throw this out for discussion.

A quarterback rolls out right, I'm following him. As he nears the sideline, he throws the ball downfield, takes two steps out of bounds, and gets a two handed shove in the back while well out of bounds. I throw a flag.

LJ comes up and tells me that the pass was intercepted and the interceptor stepped out of bounds before the hit on the QB. (While this would normally be quite rare, the pass was quite short to the sidelines and the hit on the passer was WAY late.)

So, how would this be enforced?
