What about Marshall rucking forward half 100% rather than centre square back for 80%?Ok let’s play this game. Marshall is maybe the most promising ruck in the afl. As a forward we have no idea yet. Ryder as a forward is at best average. If Marshall rucks less we have a lower quality ruckman replacing him. That to me makes us worse. If he rucks the same as he does now we have a lower quality forward in the forward line for around 100 minutes. We will be better for 20 minutes but worse for 100. The only way this works is if Marshall becomes a star forward. Even then we are worse in the ruck.
