After catching the disc, and landing in-bounds, the thrower must reduce speed as quickly as possible, without changing direction, until they have established a pivot point.
The thrower may release the disc while reducing speed as long as they maintain contact with the playing field throughout the throwing motion.
What:
An offensive player catches the disc while running and passes the disc while still in the process of slowing down.
Result:
This is allowed, provided that the player was attempting to slow down as quickly as possible and they maintain contact with the playing field throughout the throwing motion.
Extra:
Once the thrower has released the disc they do not need to come to a stop.
