I think the stoppages will be critical in this game, and we need to really study the tape from the other Prelim.
The Crows killed the Cats at stoppages, not just winning the ball but creating the player behind the stoppage to deliver the ball to advantage.
Nank needs to have a big game but more importantly, so does Grigg. When Grigg is in the ruck we effectively have another mobile player at the stoppage. If he can stop the Crows getting the ball out the their player behind the stoppage, that will really hurt them.
