She's a key position forward in a game with shortened quarters and less goal scoring. Very few if any key position forwards in the AFLW get more than a goal a game which makes it incredibly hard to gain votes. Even in the men's comp, key position forward rarely poll votes over the mids, it's just not a position to attract votes.
There's also only been 4 games of which Carlton have won just the 2. There are limited opportunities to be on the winning side so I wouldn't read anything into it. It's not an award for key position players.
