Moon will go fine in the NRL as many others have. It's easy to make the NRL to be mission impossible for Super League players but players like Mike Cooper, Josh Hodgson, Corey Thompson and many more have done perfectly fine. I see no reason why a player of Joel Moon's calibre wouldn't if that is the road he chooses to go down.

Personally I think Moon is a super player but I have doubts he is 100% fit at the moment.

Stock answer when a player isn't delivering on the field - must be carrying an injury

Followed by the stock answer from a cynic

You can't compare forwards and outside backs. The record of SL forwards in the NRL is generally very good, the record of backs very poor. I just don't see any current team where Moon would be anything other than battling to get a game.
