Puzzling is you completely and repeatedly ignore the Latu/Luai dynamic, the Benji/Moses 1 dynamic, the Galvin/Moses 2 dynamic, the Father loving Parra dynamic, the the club does not see him as a long term half dynamic, the Gus Gould dynamic...
Ok, let’s look at it:
1. The Latu/Luai dynamic - the club clearly chose Galvin and steadfastly stuck by him even when Latu was fit to play. This is despite Latu being ahead in the pecking order before season 24 began. Luai has talked Latu up and maybe this plays into the cultural thing with them both being Samoan? Luai has also talked up Galvin many times. This does not explain the attraction of Parramatta.
2. The Benji/Moses dynamic - this is rough and was used to try and get an early release and the club almost fell for it. Benji did a reasonably good job of shutting it down even though his players threw fuel on the fire. Despite how ugly this is, it doesn’t explain why he would go to Parramatta.
3. The Galvin/Moses dynamic - I’m assuming you are referring to Mitchell? Is there a dynamic? Mitch is a dominant half who is very unlikely to give the bulk of possession to a kid he doesn’t really know playing wise. Galvin craves as many touches as possible. Again, this isn’t a great partnership on paper.
4. His father loves Parra - this may hold some weight, but we are talking about a long contract possibly and that’s not a great reason to uproot and go to a club that’s struggling.
5. The club don’t see him as a long term half dynamic - This has been mentioned, but is not particular to the Tigers. I’ve heard many commentators say it as well including Joey, Freddy, Vossy, Brandy and assorted podcasters. The fact is, we have given him his start, in the halves and played him there irrespective of how he has been going. Parra may have made a promise to him. I doubt it though as anything can happen and locking yourself in to a decision like that years in advance is not good policy.
6. The Gus Gould dynamic - I’ve mentioned this more than you have. I think outside influence from powerbrokers external to his team are stirring the pot far more than is being reported. Most of the big clubs need him and finding cap space for 27 onwards wouldn’t be a stretch for most of them. As you have chosen Gus, explain how his influence equals a move to Parramatta.
So there you go, I haven’t missed or ignored any of this stuff and I am still puzzled as to why he is so hell bent to leave this club and head somewhere worse. If he winds up at the Dogs, Panthers, Chooks etc it makes more sense.
