What lumbering talls? Sure, Hooker is lumbering, but he also usually attracts a 2:1. JD and Stewart are as mobile as any defender on them, if not more so. The issue usually isn’t the “lumbering talls”, it is the extra man back giving overlapping numbers and the midfield not shutting down options out of defence which means it transitions out easily.
People seem to ignore that Richmond was hugely low scoring. They were extremely vulnerable to a team ripping them apart. Even against Adelaide if they’d kicked as accurately, things would have been square mid-way through the third quarter (and maybe further ahead if not for bad umpiring).
