Unsure why you think this is Joe's fault.
He's had what, 12 - 18 months with this squad, trying to see who can do what while at the same time trying to win every single game as there's no luxury of rebuilding.
The complaints you're making stem from 5+ years ago where there was no development of a "world class 10".
AI tells me in the last 5 years, these are the blokes who've been named at 10;
Player | Number of Starts at Fly-Half | Age |
Noah Lolesio | 19 | 25 |
Quade Cooper | 7 | 37 |
Bernard Foley | 7 | 35 |
Carter Gordon | 4 | 24 |
James O'Connor | 4 | 35 |
Reece Hodge | 3 | 30 |
Ben Donaldson | 1 | 26 |
Tom Lynagh | 1 | 22 |
3 geriatrics, 1 utility back (Hodge), 1 discarded and 3 "juniors.
Hamish fucked us by appointing Eddie and then we having to scramble to find a HC that could only give us 2 years which obviously is way too short for what he needed.
