Thereof, how does the first down line work?
When you watch a football game on television, you'll notice that the first-down line appears to actually be painted on the field; if a player or official crosses the line, he doesn't turn yellow. Colors that appear on this second palette are never converted into yellow when the first-down line is drawn.
Subsequently, question is, what has to cross the line for a first down? The ball needs to cross the line to gain in bounds. No matter where the player is. All it comes down to is: Where was the ball's furthest position on the field at the point the ball was either declared dead or forward progress has stopped.
Hereof, when did the first down line start?
