I didn't slam him for not dominating first ruck. I slammed him for ineffectual against Mark Blicavs and Tom Stewart.Some of these guys started forward, but that just reinforces the fact they were not fit enough and competitive enough in the ruck at the same age as Hayes is getting slammed for not dominating first ruck every week of his first 7 games.
We went small with the forward line because the talls we had to stand alongside Schulz were rubbish footballers.He spent ages playing as many smalls in the forward line as possible and it’s only now that we have Dixon, who’s amazing at ground level for a guy his size, and Marshall who’s a freak that kens willing to go tall.
He only likes talls who are extremely capable as smalls.
As for the rucks you named, you just gave examples of rucks known for being mobile.
What you want him to do, is what Richmond were doing until 2017, playing a rubbish player in the forward line simply because he's tall to maintain structure. It wasn't until they moved away from that rubbish decision, played their best players and set their game plan to match their best players that they won a flag. They then went to a two tall forward line because they picked up Tom Lynch who is actually a good footballer.
