Not sure the exact number that will be selected but taking into account injuries I've come up with:
Hartley, George, Cowan-Dickie
Vunipola, Harrison, Obano (No Genge, Marler to come in later, don't rate Mullan)
Cole, Sinckler, Williams
Launchbury, Itoje, Lawes, Isiekwe, Ewels (Kruis has stalled and others improved)
Robshaw, Underhill, Ewers, Armand, Simmonds, Hughes
Care, Youngs -Robson as cover
Ford, Farrell, Lozowski
Teo, Tuilagi, Slade, Joseph
May, Brown, Goode, Nowell, Watson, Daly -Cokanasiga as a power option. Included Goode as not convinced by anyone else other than Brown at 15.
