They changed that, but they also changed the throwin spot for the infraction at the same time.

So, what do we teach? Are we assuming this sideline throw-in spot in new 9.12B is erroneous, thus not to be regarded? Will a further "Interpretation" correct the error, or shall we teach that 9.12B is correct?
I'm ignoring it until further official word.
