It's close to the Ruck set up I had for about a week preseason, except I had Thurlow/Derrickx instead of Currie.
If Longer is picked, then you better rejig. If Longer isn't picked, then you can hope he also isn't picked much in the next 7 or 8 weeks, and go with Hickey. The thing that put me off Hickey is his TOG was highish last season, so no improvement to come there. Yes, McEvoy was the main Ruck, but for 2 Rucks combined. their tapouts/game was disappointing. I decided Hickey might sneak to 85-90 without Longer, and 75-80 at most with Longer. My stance on stepping stone players is well know, they need to score at a high rate. In this case, I would need confidence Hickey would average at least in the 90's, preferably 95 or higher. I don't think he will, and I think Longer will play along side him earlier rather than later. If you are happy with 85-90, and will risk Longer coming in early, go for it, otherwise rejig it.
