I think his use in tandem with Phillips is a good strategy. They are different players and that makes them harder to match up on.
I'm the opposite. Don't like the 2 Ruck strategy at all. Leaves us with less flexibility and almost a liability. Most good sides are either playing One ruck and a back up or almost part time rucks. Look at the Bulldogs this year. Hawks similar at times. It's why they chased Vickery
Personally I want to see Phillips or Kruezer supported by Rowe or Gorringe
