I see that 2021 version has been updated to reference 10.2.2.1 – thank you!
But, I’ve noticed something else that might be wrong with the same blue box (DISC THROWN > Completed YES > pick affected possession YES > CONTESTED). Currently, that blue box says “Players return to where they were when the call was made.” However, 10.2.2.1 says players “must return to the location they held when the thrower released the disc, or the time of the call, whichever is earlier.”
It’s possible that the thrower releases the disc before the pick call is made, especially in light of 18.3.1.1 (defender may delay the pick call up to 2 seconds). If the thrower releases the disc before the pick call is made, shouldn’t the players return to the location they held when the thrower released the disc, instead of when the call was made?
