I expect most of the players who will shine in the NRC will be current members of S15 teams. At the end of the Super season, only 30 players will be missing due to Wallabies' duties, and probably another 12 - 15 due to injury, retirement etc. Even allowing for the extra number of teams in the NRC, the bulk of the players will come from existing S15 teams and EPS.
From the Brumbies' squad, I expect Siliva Siliva to shine, and move up the pecking order of potential Wallaby hookers, Ruaridh Murphy and Ruan Smith to form the top front row in the comp with the Wallabies missing, Jordan Smiler to be outstanding at 6 and Stephan van der Walt to have an eye-catching series on the wing. I'm also looking very forward to seeing how Jack Whetton goes at lock. Fotu Auelua will be a standout at 8 if he's not then in the Wallabies' squad.
Newbies I'm looking forward to watching include Jonah Placid and Michael Gunn (QLD), Kotoni Ale and Patrick Sio (NSW), and Staniforth (ACT).
