All this talk of how Grundy and Max will both fit into the team positionally, might have clouded the one major benefit we can look upon next year, and that's giving Max 4 or so games of rest to keep him fresh.
He will be 31 next year and he's done as much heavy lifting as Selwood has done in the past decade.
If we look at the successful management of Selwood in Round 4, 8, 16 & 21 this year, it's a clear blueprint for how we can go about improving our fitness.
Edit:
We shouldn't be reliant on needing Max (And the injury he's carrying) in the team to win a game of football, if we're bringing in Grundy on that contract. If we were reliant on Luke Jackson and a ruck/relief alone then perhaps that is too great a burden to bear on him for 4 games, But Grundy is a different story.
