Munster was a huge loss, especially in defence, the communication just wasn't there from Queensland. I don't know if he would have been the difference, but I think his inclusion would have allowed Hunt to play that loose forward role where he was very effective in Game I.
However it starts with the back three. You can save yourself a lot of trouble by just comparing Tedesco (238m*) and Tupou (227m*) to Holmes (111m*) and Coates (46m*). Those are just the preliminary numbers, those will change over time, but any coach will tell you plays 1-3 determine who wins the set. Queensland just never got going in that department and it made it a slog.
That's the disadvantage of picking Coates. He's getting picked for those freakish efforts but he doesn't really have the ability to churn out metres at this level. It will come, it was actually his best aspect in juniors but like Tupou it's going to take time. I also don't think his future lies on the wing either, once he works on his defence, he'll end up in the centres and be a quality player.
