Player B-- throw #1 goes 500 ft past the basket. Damn headwind! Provisional throw is a hole-in-two. Does Player B have to look for drive #1?
Provisionals can never be thrown based on the possibility the first throw is unplayable, only that it might be lost. If it turns out the first throw is found and the player decides the shot is unplayable, the provisional based on the possibility the disc was lost CANNOT be used. The player must make an Optional Rethrow under the new rules.
