We needed to use 22 to get Hudson and in the end found a way of basically getting Hudson and pick 35 for pick 22.
There was no guarantee that we could pick up Hudson in the pre-season draft - he's better than the rucks both Richmond and Carlton have and both would like to have him on their list imo.
Getting a ruck was our priority and unfortunately Jordy wanted to leave. In effect we got Hudson for McMahon, Callan for Power and upgraded all the picks we're likely to use apart from pick#5.
