The thing about Mann is obvious ... He came into the team late last year and in 11 games on the wing scored 10 tries. No other wing in the team did that or even looked like doing that. So what else changed when Mann came onto the wing? If nothing else in the team changed then Mann was doing stuff that no other dragon player was doing. In terms of tries per game, Mann was in the NRLs top 10 last season for blokes that played more than a couple of games. No other dragons close to that.
If he is a stop gap measure in the team then his stop gap proved a lot more effective than the other options that were tried there.
Aitken may be good but in the highlight vid from the Tigers game he made critical mistakes that led to the tigers first try and was unable to set up an unmarked winger (chosing the throw the ball into his feet). Aitken has a long way to go to be the centre we need him to be .. He might get there, he might not. All I know is that when Milne came into right centre last season we looked a lot more dangerous on that side and didn't concede demonstrably more tries down that edge. Milne/Mann/Aitken/Lafai .. there are 4 centres going for 2 spots. None of them at this stage in their careers are must pick brilliant players. All have issues in their game .. It is going to be about picking the right blokes to enable the team to perform. Personally I think we need more ball play ability in our centres if Dugan plays fullback.
The argument with Aitken will sway to and fro, some think he's the best thing since sliced bread and some think he needs to improve his game.
We've read, he's only young and a better defender than Milne (for example) and is a good hard runner of the ball with a great fend. All this is true.
However, on the other hand is his inability to pass or even look to pass, poor lateral defence and an inability to defend the high ball. All this is also true.
Milne also has some (or many) deficiencies too, but what impresses me the most is that he won't die with the ball, he looks to set up anyone willing to run onto it and whilst he doesn't score himself, he will try to set someone else up for one. His front on defence is ok, just his technique is poor, he fends well and is reasonable agile and quick. He's sound under the high ball and laterally defends well.
For mine Aitken isn't going to win you a game at centre, whereas Milne could. Aitken should be looking to really power up his game and revert to an interchange utility. I believe he could become the most dangerous interchange player playing the game and this is where he will win us a game.
