Leilua and Rapana are causing Blair and Koroibete all sorts of problems. If the Raiders can continue to work over that edge, they'll score a few more points. Even a fake to the right before going with a Wighton or Austin could be the play for Canberra.
Melbourne are making their way through the Canberra defence relatively easily, but they cannot land the final knock out. When they're relying on Cronk to take the line on, that's when you know they don't back themselves on the shift play. I think they need to aim their attack down the Raiders right hand defence to be successful. Austin and Leilua can be very suspect, so they need to find Harris the ball and look to get the ball into Koroibete's hands as much as possible.
