I'm comparing them to no one.
Just making the point that ATM their selection @ 10 would dramatically weaken the side.
It's actually not that unusual for a side to be missing their first choice 10 & 12 for parts of the season.
You say it like it's a specific weakness of the Waratahs though. It's just a reality of having a squad of 35 or 36 people.
Beale and Foley are two of our most important players. We would be in trouble if we lost both of them at the same time. At Super Rugby level though I think we're in a pretty good position as far as depth goes.
A few years ago we started the season with Halangahu as our best option at number 10.
Due to the versatility of our backline, we have pretty good depth in my opinion.
Foley, Beale, Lance, Volavola, Horwitz can all play 10.
Beale, Lance, Horne, AAC (Adam Ashley-Cooper), Horwitz can all play 12.
AAC (Adam Ashley-Cooper), Horne, Carraro, Kellaway can all play 13.
Betham, Horne, Naiyaravaro, Kellaway, Clunies-Ross, Carraro can all play wing.
Folau, Lance, Volavola, Kellaway, Beale, Foley can all play fullback.
As far as our squad stands, I think you'd have trouble finding another Super Rugby side that boasts better options 3 or 4 deep in these positions.
