TBH I don't really blame ken for ripping into that knights player at the end there.
U can be sure they would've been absolutely giving it to him since he dropped the ball in the first set. So he had been copping shit for 80 minutes then one of the guys who was giving it to him makes an error of his own and pretty much costs them any chance they had of winning the game... I would've been into him too.
To a point.
However, what would have happened if he gave away a penalty, and Newcastle marched down the field and scored.
Brain dead act in that situation.
