Pettard is a bit of an enigma. Does some simple things very badly, then does difficult things very well. Case in point, was his over running of the ball in the Olympic stand forward pocket - nobody in front of him for 35m had he gathered, Carlton take possession, but Pettard lays and sticks a tackle to dispossess allowing us to goal in the end. The tackle was fantastic on a player breaking away, the fumble and allowing of the ball to get behind him in the first place was unforgivable )until the tackle i guess).
As others have mentioned, the goal he did kick, the ball drop looked horrible. You can tell if a ball is going to go straight 95% of the time from the drop. I couldn't believe that one went through.
On ball drops, Jacks ball drop against the Lions was very high too for some reason.
