I reckon there are so many players in front of Jetta when it comes to a 'big part of our future as a midfielder'. I think that if he makes it he'll have to play in the midfield at times, but I can't see him playing there in our primary rotation.
One of the 'mistakes' is that he looked totally cooked after any sort of involvement in the play. Regardless of any other considerations, he looked completely unfit (in AFL-terms, anyway).
