We just about need QC (Quade Cooper) and TPN to swap tackle techniques. TPN is actually big enough to execute what QC (Quade Cooper) is trying to pull off (ball-and-all/strip-the-ball) and wouldn't concuss himself as much, and QC (Quade Cooper) might start consistently stopping players. Plus I think his skull is a bit thicker than TPN's and better able to take the knocks.
He goes low and gets cited for spear-tackling, goes high and gets cited for too high. Someone needs to hit the reset button and start over.
