His (JAC) speed is something else. Genuinely the fastest player in rugby league at the moment. Love watching him get in open space, and just like Koroibete before him, Melbourne have the knack of finding space for him.
People might argue James Roberts is faster but he's been so horribly under utilised by the broncos this year you honestly wouldn't know.
I agree under-utilised, but I thought the speed with which he scored that grubber chase against the Roosters showed just how explosive he is.
Jimmy Jet has that almost instant turn of pace and strength to hold his running line, whereas though JAC takes a little longer to hit stride, I think JAC more sustained over a distance. I also don't think JAC has that strength in run to go shoulder-to-shoulder with strong defenders.
So different sorts of speed I would say. I'd back JAC in open space but I'd back Jet in crowded space.
