Can't hep but feel sad for the way Rangi's career has gone since he left Cas.
With hindsight he made a bad decision joining Salford (although his bank balance might say otherwise!). His time there has coincided with extremely bad management and a coach out of his depth.
For a player of Rangi's ability to end up in the lower leagues before his turns 30 is such as shame.
For his sake, I hope the move works out.
I can't imagine it will be long before he is asking to leave to return to SL. However, if he is happy playing in a mostly part-time league running around amateurs then he might stay
