Forgive me for focusing on this point and I'm not directing this at you. I just find it strange that there is somewhat recent confusion or frustration on a fundamental rule of football. A runner can't simply toss or fumble the ball across the goal and expect to get it back at the one-yard line. Think of it, a runner at the 15-yard bowls the ball forward to get it at the one-yard line. That's not reflective of either rushing or passing. I suspect Mike Florio, of ProFootballTalk, has made the frustration popular. I'm not biased either, I recall yelling at my TV as RGIII bumbled this play on two occasions and being frustrated by the result. That said, why do you hate the rule?
Allow me to burn your strawman for you, and remind you that you can't advance a fumble. There's a name for this, an entire
play built around it (it's called a "Fumblerooski"), and it's been illegal in the NFL for over 25 years. Fumbles that go out of bounds are returned to the place where the fumble occurred.
The only place that this changes is in the endzone, where the defense is magically assumed to have recovered. It's bullshit. Nowhere else in all of football is the defense assumed to have made a play on the ball when the ball becomes dead. It also has the really, really unfortunate side effect of turning something exciting (diving for the pylon) into not only something not exciting (failing to get the TD through no effort of the defense), but something actively unfun to watch (the defense being rewarded for happenstance) that has ruined no fewer than three games this year.
