Disagree. He was fine at it when he and Daniher were the two talls.
Exactly. Stewart just lost some form and his goal kicking had become a problem. He was still one of our best players in two of his last five matches (i.e. Hawks and Cats games).
The talk of playing roles makes no sense when it's Brown that has replaced Stewart and he's no more suited to playing as a key forward. His numbers do not indicate that he is getting to more contests, on average, which is consistent with what we see.
Brown's also gotten the benefit of playing in three wins and funnily enough he was at his worst during our worst performance of the three (when he was basically just waiting for touches out the back).
