If you read the interview of Blair Hartley on the clubs website, sounds to me he is well on top of players/clubs preferences and availabilities/openness to trades. If no offer was made it was not made because of the information they gathered.
I don't believe the club is as naive as what some are claiming, they have targeted specific players for a reason. Might have to do with the cost in terms of picks as well. Many reasons behind the scenes as to why we have gone for Maric and not another ruckman, not simply because 'Maric said he wants to come to Richmond, so lets just look at him and him only'.
