Help me out here. While technically correct that it's not a COP without a player gaining possession, by definition. Is there a situation that prevents this from being a distinction without a difference. I'm trying to think of a play situation where this matters except maybe stat wise. Maybe I'm just forgetting or missing something.
This was an issue with the OLD roughing the passer enforcement. Enforced from end of the last run when there is no change of possession. So If A fumbles on the B2 through the endzone, RPS is enforced from the B2, since technically there was not a "change of possession."
Under the new rule, this is moot, since we enforce from the dead ball spot. The above play, since it resulted in a touchback, would go from the previous spot.
