With the squad full of outside backs and Atkinson arguably the only 12 there anyway he’s the only choice (surely) Northmore has played there but much more of a 13 for me with his lines.
This should help Smith too as Atkinson can play the Estherhuizen role, can crash and distribute if needed and then find Smith space for the outside backs.
Atkinson definitely isn’t the answer at 12 but the longer Farrell is out the better
