Staying away from any risky propositions in the MID line, so that rules out Guthrie and Viney. Plus with the "discounted" options like Sloane, Rockliff, Ablett, etc., there won't be much room for these prospective picks in the MID anyway.
Bont will be awkwardly priced for a FWD at around $560k, so he's a maybe. Haven't really followed enough of Hunter to make a call on him.
Definitely the pick of the list would have to be Gray, but again, as Rowsus mentioned, it all depends on his role in the team, and whether we can rely on him for 22 games.
Good input.
