This has been Goodwin's tactic (and my complaint) from the moment he took over. I suspect that they are working on the theory that they will either take the mark or one of our small forwards will crumb after Hogan/McDonald/Pedersen/Gawn crash the pack. Unfortunately there are a couple of glaring issues with this plan.
Firstly, our forward line coach as yet to teach our forwards to work together. When the high ball comes in we invariably see every forward in the vicinity try to mark it, often spoiling each other and winding up with most of them falling over. With nobody staying down it is a simple matter for the opposition to crumb and run the ball out of the 50.
Secondly, because we are so very predictable in this tactic, defences are setting up specifically to counter this play and generally getting their structure in place before ours.
I think a great illustration of this came last year when the Weed was playing. In one of his games he twice took a mark just outside 50 on the boundary. Both times he looked around for options before deciding to follow the team rule and hit up the Hot Spot. Unfortunately on one occasion the only people there were from the opposition and on another we had a single forward against three or four. To me it looked like he had clearly been told that that was what he had to do after taking a mark at HF, and sadly he did as he was told instead of making a smart football decision.
