Mike, as SDUMP stated, if the ball is touches the pylon and the runner is still touching inbouns, we have a TD. In order to touch the pylon, the ball must first break the goal line plane.
If the runner is not touching the ground inbounds, the ball is OOB where it crosses the sideline.
The case play you're looking for is 2.25.3.
BTW, this gives me a chance to put in a word for Athletic Rules Study. I'm sure most officials understand how valuable the exam practice can be. However, the CD also has the rule book, case book, and funny book on it. I copy those files, and the accompanying support files, to my hard drive and place shortcuts on my desktop. Now I have instant access to those manuals if a question pops up on a discussion board. Also, each book has a great Find feature. For example, I type "pylon" and a list of every play with the word pylon appears. What a great study tool!
Buy it and try it!
