There's about the same chance of Wright flubbing the recovery to the benefit of the lions as there was in a forced fumble in at the one yard line that goes out the back of the end zone. Except that actually happened.
Again, you keep making the assumption that it would not have affected the play. Chances are you are right. But chances are that Calvin scores on that play too, and that didn't happen.
The bottom line is that Wright illegally affected the play and we simply cannot know the outcome had he not done so. Your PI non-call illustration is not the same thing, since that happened no where near the play. This non-call WAS the play.
