CCJ and Balta need to have big preseasons. If they can improve they give us a second (and third) ruck and more marking power. I know they have a long way to go but they have the talent to be very good players. 
Are you saying we now need 3 rucks at any one time or that we need the depth of ruck options?
I’m expecting Tommy Lynch to take over the pinch hitting from Grigga.
Balta is our back up/replacement for Broady.
Tom Lynch won't ruck. He's just coming off a PCL which is the ligament that goes in rucking duels. He'll play deep. Jack will play higher up the ground as a CHF but can also alternate with Lynch. CCJ is a pure second ruck but has great hands around the ground. Balta is more like Rance in the way he could play. He can pinch hit in the ruck but is also mobile and has pace. He should play down back and run through the middle. Also an above average mark. That suddenly gives us more height, marking power and we don't lose a lot of speed. I would have Balta taking Houli's spot and CCJ taking Griggs. Suddenly our balance is much better.
Ruckman who have had PCL’s go back into the Ruck, why wouldn’t T Lynch if he’s fit and well?
Balta replacing Houli? I’d like to see him back, possibly replacing Broad who had an ordinary year and look to Markov to replace Houli - he has the run and carry with hopefully another strong pre season under his belt the running capacity to match Houli.
CCJ might make us a bit too heavy in the forward line with Lynch and Jack down there as well?
I see him as back up to the Nank.
