Assuming Lima is selected, I think we'll see Miller, but I don't think we'll see Umaga.
The problem with having Miller and Umaga on the bench is the cover for the centres.
I know Jacob covers 12 as well, but it's one thing having him on the bench to cover 10, which is presumably his primary position.
It's a whole different thing having him cover 10 and 12 from the bench.
For that reason only, I'm gonna assume a bench of Miller and JdJ.
I'd love to be wrong though and see what Jacob can do in the prem
