If Hetherington stays true to his word, these are some of the changes i can see happening, and just a general guess at where the players might go, and some of the changes i would make

Released
Brent Webb (Catalan)
Paul McShane (Widnes)
Kylie Leuluai (retired)
Lee Smith (London)
Ian Kirke (Wakefield)
Richard Moore (Featherstone)
Weller Hauraki/Chris Clarkson (Widnes)
Luke Ambler (Halifax)

I'm torn with Hauraki and Clarkson as i like both as a player, but with some of the potential changes one may have to be sacrificed.

With that in mind, these are the changes i'd make:

Jimmy Keinhorst (4)
Danny McGuire (7)
Rob Burrow (14)
Darrell Griffin (19)

Brad Singleton (21)

Ollie Olds (26)
Jamel Chisholm (27)
