One of the most underrated aspects of modern hooker play are the bullet 20-30m passes straight from dummy half.
Defences are so good on the goal line now (i.e. offside), but the ball moves faster than the player... and a 30m bullet spiral from dummy half can beat 3 defenders in an instant and suddenly the half is outside the 4-man and making a beeline to the edge.
Souths attack was so potent over those previous years, because Cook's service and ability to throw those long passes instantly got Cody outside his inside defender and it's Cody, Latrell and that left side up against 3 defenders.
I'm not sure that Bhunt has that in his skillset, but Walters and Paix don't seem to have it... I haven't seen enough of Mozer to know if he has it, but he looks to have the best pass out of those 4.
It probably is something that Mahoney has, and I'd say that's what cows are talking about when they talk about service from dummy half.
You can base your whole goal line attack out of that kind of pass.
