Is Bridge being rested?
I wouldn't read anything into the selections at this stage. They'll give most of the squad a run in the first few games
I remember 1014 mentioning match day 23's in 2015. Basically the selectors tested a few players out early and then dialled their squad in. Each Test got closer and closer to the RWC side.
So for the first Test in 2015 (v Samoa) there were 9 players not named in the RWC squad:
Andy Ellis, Charles Piutau, George Moala, Israel Dagg, Hikawera Elliot, Nepo Laulala, Matt Todd, Brad Webber, Charlie Ngatai
The 2nd Test (v Argentina) there were 5 players not named in the RWC squad:
Charles Piutau, Israel Dagg, Nepo Laulala, Jeremy Thrush, Andy Ellis
I suspect Hansen will follow a similar pattern this year. This 23 seems comparable to that game v Samoa
