This was Billy's first go as a coach (well head coach) anywhere and by all accounts was fucking brilliant at it. Real attention to detail. Also helps that he brought in guys like Cam Smith, JT, and Josh Hannay who appears to be a good coach.
A big part of Origin is bring a bunch of quality players together and pointing them in the same direction, and you get a week before each game. So it's man management as much as anything. And selecting. But there is still a level of game planning and attention to detail that is required.
Freddie appeared to be a bit of a vibe guy, creating a nice atmosphere in camp, and relying on established club combinations to get them home. His best "coaching" performance was in the peak "6-again" era where he just selected as many fullbacks as possible and they ran riot against a far inferior opposition. It very much look like he just got out of the way and let Turbo and Latrell carve up.
Good Origin coaches don't necessarily make good club coaches, and vice versa, but Freddie was a shit club coach, and Origin hasn't gone that well either...
