The big question mark for me still sits around R. Warnock. Love him as a player, but given Mick has never been one to adore ruckman in the past, I still think something could be going on. The fact is Kreuzer, Hampson, Casboult and Warnock are probably going to be competing for 2 spots. In the past Mick has gone for the 1 genuine ruckman, which we can assume will be Kreuzer, and the KF/2nd Ruckman. Leaves Robbie as the odd man out, even though he is a superior tap ruckman to MK.
Robbie has the potential to be an a-grade tap ruckman, but it's very hard to see him playing lots of game next year, unless MK goes down. Amazing depth to have for us, but the question for Mick, is would he rather have a good ruckman waiting for a chance in the 2's, or trade in another first round pick or player.
The other option, which is seemingly less preferable, is if MM see's Kreuzer spening more time forward, with Robbie as the #1 ruckman, in which case Hampson is likely to be waddling around in the 2's.
