I don't have my books here and wanted to make sure I had this right.
A's ball 4th and 10. Run ends 2 yards short of the LTG. After the play is blown dead B commits a personal foul.
I was thinking that because B's foul was a dead-ball foul it's now B's ball and enforce the penalty with B having a new series 15 yards behind where A's run ended. Correct?
