If he is serious about Tuilangi long term at 12 that could have further balance issues for the back line. Ideally we want a balance of distributors, strike runners, kickers and gain line breakers.
Joseph is great but is only an OK distributor/kicker (he has got better in this regard). With Brown at fullback offering little in distribution terms, this would leave us short of ball players, especially if Farrell is at 10 - he is just not as threatening as Ford.
I can see why he might want to get a gain line winner into the back line. It creates space, holds defenders and adds an offloading threat. He also seems to really like Ford and this may be why he wants a big 12 - Ford can afford to stand flatter with the threat of Tuilangi at 12, putting him right on the gain line, passing behind Thilangi when defenders are fixed or looping round off him. It also makes wingers coming off their wing more effective and makes a Ford break more likely.
If he sticks with Joseph then for me Goode has to come in at fullback as a distributor/kicker (Goode has also done quite a lot of speed work which seems to have improved his major flaw) - Brown is also likely to be too old as a back for the next WC. Alternatively Daly with his better distribution and kicking game replaces Jospeh. Or maybe Slade comes in at outside centre (he has virtually no experience of playing inside centre in spite of this being the spot he has been earmarked for and is going to get none At the Chiefs with Devoto and Hill). If he wants to play Ford at 10 Daly/Slade's long range goal kicking would also be useful. Ford is a fine goal kicker until he has to push his range. His % is actually slightly above Farrell
These changes could only take place over time. Daly has the complete skill set to be an outstanding international but sides that have changed too much too early have often struggled to build momentum.
A possible back line summer more probably Autumn internationals
Youngs, Ford, Nowell, Tuilangi, Daly (Joseph) Watson, Brown (Goode).
