Brad Arthur at the Leeds Rhinos is a ten year NRL Vet coach right?
Before him Rohan Smith is son of the Legend NRL coach Brian Smith.
They use BJJ coaches in preseason at Leeds.
As I keep saying, don't assume based off some rando comment from a poster having seen a two second short clip that a player is destined for NSW cup and short on defensive skills for the actual sport, that is a mega over reach.
Whether or not
Gannon needs NSW cup time is a subject I am neutral on, because I don't know as much as those that are sure it is a fact are pulling it out of a hypothetical ass.
I will leave that up to the coaches and won't be watching two seconds of a preseason clip and using it to pad a very generalist narrative to suit. Because frankly that is a lazy way to form an argument.
