Mate, did you ever watch John's kicking game? Torpedo, banana kick, deliberate grubbers into the pads. He pretty much reinvented how modern halfbacks play.
Passing game, short pass, long cutout pass onto players chests to put them into holes.
He wasn't fast but the way he could skip, hop, double pump and then wrong foot defenders just shows how good he was that he didn't rely on pace to make a line break.
That Buderus try in Origin where he bounced around and tunneled the ball back inside between defenders to find Buderus was ridiculous.
He was really good at spotting tired or weak defenders and exploiting them.
