I get the impression we are tweaking our forward line a bit and some players are taking a little time to adjust. I am guessing it might have something to do with having Lynch in our forward line, and the different way he brings the ball down to ground in a marking contest. Lynch seems to predominantly bring the ball to ground in front of the pack, where as Jack seemed to be a bit more sideways or behind the pack. Rioli, and Butler for that matter, seem to be much more dangerous running onto the footy going towards goal rather than hunting across the pack.
George actually looked pretty comfortable last night. He looks much better kicking for goal across his body, so if Lynch does bring the ball down forward, I think that is George's go. His tackling, as has been mentioned, is very good, particularly front on tackling, where as Rioli is a much more a run down tackler.
Ellis for the second week in a row has snagged goals, and last night they were deeper in the forward line than I think I have seen him lurk before. McIntosh is another who seems to be consistently pressing further forward than in the last couple of seasons.
Conversely, Baker seems to be playing further up the ground.
I dunno, just some observations that might be way off the mark.
