Backline - Gov, Barrass,Schofield, Mackenzie (3 max)
Forward line - Kennedy, Darling (2)
Rucks - Naitanui, Lycett, Giles, Vardy, Petrie (2 max)
Resting ruck can play as a third tall and gov can rotate forward depending on matchups / game situation
As others have said anymore than 7 is madness and arguably 7 is one too many
