Definitely you needed to start 2 of Goldy/Gawn/NN, otherwise the damage is done.
Gawn has been a monster and a beast so far, his ceiling is the part I'm terrified the most as it can be the difference between winning and losing league matches. The Demons centre bounce setup is amazing and Gawn just knows how to feed them the ball, would not surprise me if he is way out in front in the H2A stats.
NN would be the equal of Gawn if not for his low TOG%. With Lycett doing so well, the Eagles seems to be taking a conservative approach to NN when their games are decided early. I just hope that the Eagles plays in more closely contested game as this is the only way NN is going to spend more than 70% TOG.
