I'll assume Hindy and Nathan Cayless will honour their long term contracts, so other than them it would be....
1)Wade-We have had some good fullbacks over the years (Schifcofske and Hodgo in recent times) but McKinnon looks to be one who could really nail down the spot and perhaps future rep duties. Tough as Hodgson, and as good in attack as Schifcofske, the weight he put on in recent years has helped his game so much.
2)Johnny Morris-Goes well at hooker, half or five-eighth. Very smart player who can run a team around the park. Good solid defender, gets out of dummy half well and has a good kicking and passing game. My long term five-eighth choice
3)PJ-Assuming he gets back to his best after a long term injury, PJ is still one of the most damaging players in attack in the game today. Can play the same positions as Morris, and can also guide the team around. Is still young, and already has State of Origin Duties under his belt.
4)Eric Grothe-Was picked in the 2000 Origin squad before injury ruled him out. Showed us what he is capable of this season with some fantastic tries, and completely dominated opposition outside backs. If he can stay fit, will most certainly be a rep player in the next few years
5)Pig-I've always thought he was a similar player to Hindy, just without that insane stamina. Can turn a game with one run or dummy half barge over, and is a very good goal kicker. Also an experienced leader and a character who could form part of the teams foundations in furture years.
6)Morrison-Similar player again to Hindy, but probably a tier below him. Works hard, defends well and has played City-Country. Also a reasonably young player who is used to being part of a leadership group.
7)Dean Widders-One of the best players to have coming off the bench for you. Like Riddell, he can turn a game, but Widders will do it with his surprising turn of pace and side-step.
Youngsters.......(I haven't included reasons because I have only seen bits and pieces of most of these guys, but have been impressed)
Blake Green
Tim Smith
Ben Smith
Afa
Cannings
Daniel Backo
Brett Anderson
There are probably others I'll add to my "wish list" after next year....
