"Tinney reading through the rules on when a tackle may be considered unreasonably dangerous. Relevant here is that the arm of the player was being held, which made it 'a tackle of an inherently dangerous kind'. Dangerfield was unable to control his movements or protect his head. Also to be considered, 'a player may not be slung or driven into the ground with an excessive level of force'. Tinney suggesting the same outcome could have been achieved with considerably less force than was used."
Sounds as if he's gone.....
