Jake White's only error last year, imo, was to try to fit Ita Vaea at 7 in the early games, following the SA model. The Reds played two fetchers against the Brumbies and won easily largely through glut of possession. Hooper then started, and we know what his impact was for the rest of the season. I think a fetching 7 is still the best way to go.
The pleasure of rugby is that it depends on the gameplan.
The Reds countered the Brumbies gameplan, but the two fetchers should weaken both the lineout and scrum, more mature tactically sides would have/should have been able make the Reds pay a bit more.
