Regarding drafting ruck men, I think 18yo ruck men are not up to it, they take too long to develop and when young are injury prone.
We need to be looking for a 24/25 year old who is not getting opportunity elsewhere as per Toby.
I am sure our club has a view on who is in the mix
I disagree i think you need to do both.
Most list have enough room for four ruckmen most have a genuine fwd ruck in that 4.
Incumbent ruck Nankervis, Mature or at least developing back up ruck Ryan a bust so far , Junior ruck of which we dont have one, and of course the fwd/ruck at this point in time Sims.
It says to me depending on how you rate Ryan the need for both a mature back up and a highly promising one to develop. Then of course there is the long term mature project cat b basketballer which imo is an exercise in feeling good.
