I've never claimed he is a champion. I think that we do not know how good he could be because he has never had a decent pack. But I think he has enough talent to perform well in a good team.
We don't know if Thurston, Cronk, Cleary would perform behind poor forward packs. They've rarely had to. I think they would still perform better than Brooks has, but not by much
Will the new look pack be enough? Well, first they need to perform to their potential. Is Bateman really coming and if so is he still an elite backrower or is his body breaking down and he a shadow of his former self? Will Papallii have the motivation to perform in a side he reportedly didn't want to be in? Can Utoikamanu perform to the expectation we had of him post 2021 or will he continue the struggles he had in 2022. Most importantly will our starting pack stay on the field or will injuries/suspensions mean we are relying heavily on a bunch of kids?
If the forwards do in fact perform to their abilities then yes they are good enough that Brooks should thrive. If the forwards perform to their abilities and Brooks does not perform I will be happy to attribute blame to him. But, I won't blame the results on a halfback that is playing behind a poor pack as Brooks has his whole career.
And back to my original question what did you rate about the pack in that 4 year period? I argue they weren't that good because they weren't. I would love to see an argument that they were.
I think I read yesterday (can try to find confirmation later if you like) 2015 we ranked 15th for running metres. Then the pack imo got worse in 2016 and 2017.
