Fumble Advanced for a Touchdown

[Warrenkicker]

Perhaps they want us to think about where the penalty would be enforced from. On this play, the spot of enforcement would be the end of the associated run at B-45. Now if there was no fumble and the penalty still occurred as described then the spot of enforcement would be the end of the run at the goal line. But because the ball can't be moved further into the endzone and "really" make it a touchdown we are told to enforce it at the succeeding spot. So I would say that on the play as described they might want us to have A decline the penalty to keep the touchdown. However the book, as written, does not support this idea.
