I agree that a quality THP is essential to allow HJH (Harry Johnson-Holmes) to return to the LH side where he was developing as a real Wallaby prospect.
Who would the Tahs be likely to recruit that is better?
How long (if at all) will HJH (Harry Johnson-Holmes) stay ahead of Bell at LHP?
I don't think there is a strong likelihood that he will be moving and I'd argue that Tupou and AAA are the only THPs better than him in the country.
For whatever reason the Waratahs have had a weak scrum for a number of years. The same front rowers look much better at scrum time for the Wallabies than they do for the Tahs.
