Where does world beater come into it? You said quality, which, while accurate in a number of areas, has two of which are rubbish.
Leota and Ekuasi, while not at the same standard as pure 8s for the international arena as Valetini, Gleeson or Wilson are, are very good Rugby players and at Super level are more than capable of slightly adapting their games and providing a different but equal impact to those players.
And while Anderson lacks an individual "elite" attribute that will garner him any extended international selection, he has a very strong all round wingers game: he has the size, pace and rugby intelligence to be a strong carrier and good finisher, and an excellent defender, particularly in one on one tackles and at the ruck.
Those aren't positions I see us being exposed in.
You obviously don't hold a high opinion of Daugunu so I won't linger on him (note I did not indicate the 11 jersey either) or any of the other wing options, but in addition to the issues at scrum half and inside center you highlighted, we lack depth at Lock after the two starters, we lack a back up stand off, and both our 1 & 2 hookers have had extensive issues with throwing. To me, those are the obvious "playing squad" issues which our season will depend on, not which players start at wing or 8.
