Think it’s been said that Sirker has still been adapting to the 15s game which would make sense considering the A league had a break where he could work on his game before coming back with a bang for this block.
Think there’s also something to be said about the way the team are playing- they’re putting players into space and Umaga is central to that.
Lastly there’s a good balance of players, half academy, half senior players needing game time and no guests. Shows some sort of collective and continuity that can’t be underestimated.
