I think you're missing my point.
The Roosters are appealing to shortsighted young players because they think it's an easy ticket to the GF and rep duties.
Other players may also find Canberra unappealing because of the weather, the supposed ennui, the lack of family and friends, etc.
If Joel really thought about it he should have realised that this team is still pretty competitive (including his valuable contribution) and that he would still have challenged for an origin jersey with good, consistent, form.
I'm sure Stuart and Gould were in his ear about rep duties, and that pisses me off no end and reminds me that rep coaching duties and administration should be club-independent so they can't be used as bargaining tools.
There is only so much the Raiders management can do to attract players who don't want to play for the club.
Congratulations to Carney, Weyman, Schif, etc for seeing the light.
