Most players that could work out don't want to come to this destination (frustration) club eg. Luke Lewis.
They know that they would have to work their guts out to even have a remote chance of any sort of success at this club, so either they pass up on coming or if they do come, treat it as an early retirement and just go through the motions knowing that this is their last contract, why knock yourself out.
One would have hoped that Api and Papali'i signing would have opened the door for others to come, but while we are not winning games and copping crap in the media I just don't see this being something that is going to happen in a hurry and having new teams coming into the competition certainly doesn't make things any easier.
