If an offense takes a 10 yard penalty inside their own 20, it should still be a 10 yard penalty. The ball is moved back half the distance to the goal, and rest of the yardage is added to where they have to go
Ex, 1st and 10 at the 12, need to get to the 22 - 10 yard holding penalty, now it’s 1st and 20 at the 6, and they now need to get to the 26.
