Enigma
Reserve Grader
Instead of standing around looking at a teammate desperately try to free his arms to offload, why don't players go in and extract the bloody thing in person at no risk and wait for the Ref to blow that whistle as a try is awarded. Same thing if he is held up over the line but still alive, just borrow the thing and plonk it down. As far as I am aware theft of the ball from your own player is legal.
