I believe there is a BIG misunderstanding here. A foul CAN be both Targeting and RTP. I direct you to the second CFO training video on targeting with Walt Anderson. In this clip, it is clearly stated that some RTP calls are targeting and carry the automatic DQ and some are not. In this case the foul would be "Roughing the passer by targeting." This foul carries a 15 yard penalty tacked onto the end of the run and an automatic disqualification. It is a RTP foul with the additional penalty of an automatic disqualification.
It kind of amazes me that at this point in the season and with how long the targeting foul has been around that you would still have college officials thinking these two fouls were mutually exclusive.
