I imagine team lists will be posted before they play each week, but it is made up from the Reds Academy and any top squad member who is outside the top playing 23/25 that week, that they want to get game time for. It fills the gap between when Super Rugby starts and the club season, so players can get meaningful game time incase early season injury and good exposure for players and something different for clubs to play against. Fairly good representation from most clubs I think, in terms of where players come from
