You're right. I'm pretty sure Carney and Wade did an inside outside play or Melbourne/Queensland play. We've scored using that play recently, may have been against the Panthers. I think a play like that can become predictable, that's probably why they don't run it all the time.
On a slightly related note. There was one guy behind at the game last night who said "you wouldn't want to be a Sharks winger, you would never get the ball" and last night that was so true. In the second half especially, the ball didn't go much further then the centre on the left hand side. I've never really noticed how many inside balls we throw but the view I got seeing the guys from behind in attack made it look so obvious. Robson look like he made a nice run across the field, only to turn it inside to someone else. Bloody infuriating.
