I think we need class up front, of any size. As we have seen in previous years collingwood, richmond (2017) and west coast have been contending with different mixes of forward sizes.
I think Harmes could be moved to play a large percentage up forward. Hes got good size, and would give us great ground level presence, plus loves a goal. This would free up a spot in the middle for Gus, whose form dipped when moved to a wing.
I think we also need to pray that Fritsch, Trac and Weid take the next step. Only time will tell.
