James,
Without my books, I won't argue the kick any further, but in the pass play, if B85 is in a position to catch the ball, it certainly wouldn't be pass interference because he established position, it could actually be Offensive Pass Interference, and I respectfully disagree with you on the fact that you can't establish a position and keep it. But again until I get my books back out I don't have any rules reference to help with my case
