A lot of comments on Noah from both sides of the fence. My views is Noah is not in the team for 2 reasons and both affect the team negatively.
1 - He goes down far too easily with life changing injuries and then bounces back up 1 minute later, but we have been exposed the other way
2 - He's in his head too much. Much has been made of Noah vs MRJ, why is 1 in the team and the other isn't. I'll go back to the Sydney game. MRJ's 1st half he'd won something like 8 or 9 disposals with only 3 being effective as he turned the ball over a few times in the corridor. He didn't let his head drop though, he kept doing that and from then on he had a similar number of touches but was at about 80%odd, whilst continue to play to instruction and take the game on through the corridor. I have zero confidence that Noah would have done the same, he dwells on mistakes way too often, we've seen it happen in the VFL and the AFL and he then either over tries to correct the mistake and makes further errors, or he goes into his shell.
People looking for more info as to why he's not in the team IMO are looking into it too deeply. I believe the above are the reasons.
Number 2 in particular will be fatal for him if he can't correct it. AFL more than many other sports, you make more mistakes due to the speed, intensity and endurance impacts of the game, but you cannot dwell on the errors, you simply have to move on to the next contest, but Noah doesn't seem to be able to leave those errors behind unfortunately.
I really hope he can as his skill level is very good, and he's exactly what we would love to have in our forward line.
