Hypothetically,
If Carlton had already been in talks ( behind closed doors ) with Warnock pre- 2007 National Draft. And it had been determined that at the end 0f 2008 he would become a Blue.
Would you have still taken Kreuzer ?
I think NOT.
Our ruck division without Kreuzer would then be Warnock & Hampson, with Cloke pinch-hitting as an undersized ruckman. Given Hampson is a project ruckman (has been playing Aussie Rules for about 4 years only) & Cloke is not a long-term ruck solution (his future prospects lie as a forward), that leaves Warnock.
Kreuzer was the best ruckman available in the 2007 draft & had been the best player in the TAC Cup competition in 2007. Most of those 'in the know' agreed there was very little between Kreuzer & Cotchin at the top of the draft. Given we had secured Judd prior to the 2007 draft & that there was virtually nothing between Kreuzer & Cotchin, we went for the big man, because good midfield players come along a bit more often than good big men. That is demonstrated by the availability of players like Hamish Hartlett, Jack Ziebell & Steele Sidebottom, among others in this year's draft. And before you point to Natanui as a good big man, he will be a project player, who will most likely not adapt to AFL football as quickly as what Kreuzer has & won't be available to us anyway.
Moving forward, a ruck division of Warnock & Kreuzer is better than a ruck division of Warnock & a project ruckman & a shorter, pinch-hitting ruckman.
