As a matter of history, when David Nelson was the Sec-Ed of the rules, the line-to-gain was set immediately when the ball became dead, and Team A would, indeed, start with 1/25. That was something about which he and his great friend and colleague John Adams disagreed for many, many years, but Mr. Adams could not get Mr. Nelson to change. So, when Mr. Adams succeeded Mr. Nelson as Sec-Ed, that was just about the very first thing he changed. He, and most coaches, I think, just didn't think it was good for football to have a team begin a new series with 1/25. The distance penalty was enough. Let them begin 1/10.
So, there you have it.
