If you claim that the previous spot is actually previous line
I have not made ANY claim on this thread -- review my posts carefully. I have simply a) asked for ACTUAL rules support and 2) stated that I haven't seen it. After a very careful review (~45 minutes), I still haven't seen CLEAR support for the idea that the previous spot is ONLY the blade of grass (if you will) that the ball was snapped from. I'm NOT saying it isn't; I'm just asking for rules support here. If you want to call that obtuse, fine, but it doesn't address the issue.
The problem with the idea that "point" means something here is that the word "point" is used to define most of the "spots" defined in Rule 2: enforcement spot, previous spot, succeeding spot, etc. The enforcement spot for basic spot fouls BEHIND the basic spot are enforced from the spot of the foul, right?? So let's say we have Team with a simple run play to the left that ends up dead in the left side zone. But we have a Team A face mask foul on the right hash beyond the neutral zone but behind the end of the run. Where, according to the rules (assuming accepted penalty), are you going to position the ball and why? The enforcement spot AND spot of the foul both have "points" in there defined just like the previous spot does.
