A and B are exactly the same. I find it helps to think of
the field excluding the attacking endzone as the "playing
field proper".
At least that's how I interpret the rules. I'd appreciate it
if someone could confirm or refute this way of thinking
because it has some other implications which seem to
contradict popular belief.
1. Since the front of the attacking endzone line is part of
the pfp, it's OK to set your pivot ON THE LINE after you've
run into the endzone and you need to come out.
2. The sideline is considered out of bounds so you need to
set your pivot foot IN THE FIELD after running out the side
(or putting the disc into play after a turnover out the
side). Pivoting on the line is out and throwing from there
is a violation.
3. After the other team throws it out the side of your
defending endzone, you should put the disc into play inside
the cone because the cone (or where it was) is considered
out. You may find that the cone gets in the way of your
sweet fakes and kicking it looks cool so go ahead.
4. On unlined fields when you're trying to establish whether
you were in or out, it's actually a separate matter whether
you were in the endzone or in the playing field proper. If
you want to know if you were in the endzone then you use the
cones surrounding the endzone (cones are not in the
endzone). If you want to know if you are in the pfp then you
use the cones surrounding the pfp. In other words, use the
cones you are between, not the cones you are attacking.
Is that all true?
