Can anyone refute any of the statements?
Yes, and it's already been done in this thread.
NO penalty may be enforced more than half the distance...(except for DPI).
This statement is only partially true, and that is why half the distance does NOT apply here.
10-2-6 specifically says a penalty can't be more than "half the distance from the enforcement spot to the
offending team’s goal line" (emphasis added). This penalty is committed by
Team A, but moves the ball toward
Team B's goal line. 10-2-6 does not apply here.
