Just forget the name "Aaron Hall" for a moment: a player has had 23, 33, 33 and 37 disposals this season in the full games he's played, has a good bye, an extremely friendly role, is priced ~ $420 k and plays in a problematic area for Supercoach. You think that player is not at least worth considering for team inclusion?
It's mostly all about the role and the situation, and only a little bit about the player. Hence the reason Ziebell and Impey look to be top 6 forwards this season, and why, for example, Darcy Moore looks like Supercoach elite when he has a role change, like he did yesterday.
I will note that the winning DFS lineup on Draftstars yesterday (for over $7k) had the North/Pies game stack and I think that will continue (ie, whoever North are playing plus Hall/Ziebell) while the prices of those North players are as low as they are relative to their output. Yesterday's winner had Hall, players like Maynard, Moore, DeGoey etc to claim the top prize.
It seems inconceivable to me that they'd drop Hall, he's one of their few winners. Yes, he could have a role change but we'll deal with that if and when it presents itself. The injury thing does bear more scrutiny but at the moment he looks like a gift horse some are going to look at in the mouth of because of his name.
