I think you're missing that, by definition, an "overthrown" ball is one that has either been thrown into dead ball territory or has become blocked. So 8-5-G-EFFECT is what applies to a ball thrown into dead ball territory or has become blocked. The exception you see for a blocked ball applies only to when the ball becomes blocked by offensive equipment not involved in the game. The definitions can be found in Rule 1. This specific definition is on page 29.
Not a bad idea for the trophy, I got a player that could throw one throw a goal post at 100 yards . Love this Game
. Would the Trophy have a coach crying and beating his fist on the grown, or swift kicking her dearie
