British Rugby League is not in a position to let promising young backs like this to to union. I think Rugby League has lost this player for good.
I would hope he's not replaced with a has been or never was player from the NRL for the good of British Rugby League.

Good job he's not a promising player then.

He was clearly not good enough for SL, his tackling & positioning are abysmal.

Also worth noting the last player Leeds took from Cas was Hepworth...so they're not exactly great at spotting "talent" from Cas, are they?

No loss to league at all and it's addition by subtraction for Cas, Blackmore & Clare are both better.

With over 4,000 posts to your name I thought that you'd post some sense Gronk! but deary me do you talk rubbish. How can you claim that 2 players (Blackmore & Clare), with less than 5 SL games between them are better than Josh Griffin. Yes, he (JG) has had his problems but he has improved immensely over the past month. He, along with Youngquest are our top try scorers this season and in a struggling team Josh has given us a good return. I only hope that Griffin leaving has opened up the possibility of us signing Rhys Williams on a permanent deal. I would be very excited to see a Tigers back line of Owen, Williams, Shenton, Webster, Carney, Chase & Ellis starting 2013.

Woo he scored some points his terrible defence will have given up more than he's scored.

Ooops sorry, nobody is allowed to say anything bad about Cas when you're around

Although bringing in Williams wouldn't be a bad thing.

I completely agree Gronk! I think his defence is shambolic and he has the heart the size of a pea, hopefully we can bring in a decent replacement

I would prefere Williams myself but I can see us having Carney and Clare as our starting wingers next year.

Thank god for that he is one of worst wingers i seen at Cas please replace him because i think thats 12 left and only 5 signed we alreay have a small squad.

Disappointed. I, like others, saw potential in his performances for the future. Good luck to him.

He's gone to Leeds Tykes who are a poor RU club, and he had only plied (or tried to) with poor RL clubs. If he is such a loss, I wonder where the big clubs are with their offers??
Personally I think he is at his level, and whoever is his employer is getting a poor rugby player who seems to have higher views of himself than any of his previous employers who have sought to replaced him with better players.
IMO of course!!

Not a bad player, but at best only average.

shame,he would of improved considerably next season with better players around him

plus our squad seems to be getting smaller,will struggle to have 25 players next season

Griffin has everything required to make it at the top level - only injury or lack of ambition can stop him. He's only young and his best years are ahead of him. As for his poor defence I suspect that's as much to do with the general poor playing patterns within the team as much as him. Wingers are always more exposed in these situations, though for me he was always a centre anyway.

Vasty - I remember saying exactly the same thing about Wayne Pryce.

Had some potential but cant say that i will miss him too much. Didn't help his cause by giving fans so much stick either.
