second player. Collingwood drafted cousins Brayden and Heath Shaw using their second- and third-round selection, respectively, in 2003. Bidding system In 2007, following concerns that potential first-round draftees were being selected for an unfairly low draft pick under the father–son rule, a bidding system was established to ensure father–son recruits could still be preferentially drafted by the father's club, albeit at a fair market value. Under the 2007 amendment, any club could bid on another club's son with one of its draft picks, and the father's club then had the right to recruit the son by giving up its next pick. The bidding process occurred prior to the draft, but the decisions made while bidding were binding during the draft. For example, in 2008 the Western Bulldogs used their first-round selection to secure Ayce Cordy after St Kilda bid its higher first-round selection for him. The bidding system was further refined in 2015. Under the current system: Each draft pick is assigned a value (with No. 1 starting at 3000 points, declining exponentially until No. 74 which has no value), which is regressed from historical player salary data. During the draft, any club may bid for a father–son eligible player with any draft pick. The father's club, if it wishes to select the son, must then use its next one or more draft picks until the total points value of the surrendered picks adds up to the value of the draft pick used by the bidding, less a discount – which is either 20% of the bid value or 197 points (equivalent to pick No. 56), whichever is greater. Any points left over after reaching the bid value result in the draft pick being shuffled down the order. The club which originally made the bid then has the next selection in the draft. The same bidding process has also been used since 2015 by the New South Wales and Queensland clubs to gain access to their states' academy players. Player eligibility As of March 2011, eligibility of players differs depending upon the home-state of the team making the selection. All clubs A player is eligible if his father played 100 or more senior games for the clubs. In the cases of the two interstate clubs with historic links to Victorian Football League teams, namely the Brisbane Lions and the Sydney Swans, the sons of players who appeared 100 times for
