Frost and Brown both moved during the trade period to the Brisbane Lions and St Kilda respectively, while Marsh - contracted for 2017 - has asked to move back to Western Australia for personal reasons. Collingwood have chosen to keep Marsh on their list for now. While the Pies landed Lynden Dunn from Melbourne during the trade period to bolster their backline stocks, Keeffe will help will the void in defence. Meanwhile Collingwood confirmed that American big man Mason Cox will start his third year at the Holden Centre on the club's rookie list. There was considerable movement around the league on Monday as father-son nominations and first list lodgements closed. Adelaide can recruit Ben Jarman if they want him after Hawthorn decided against nominating the teenager as a father-son selection in this year's draft. Jarman - the son of former Hawks and Crows premiership player Darren - was eligible to be nominated by both clubs given his father played more than 100 games at both. However the Hawks released a statement ahead of Monday's deadline confirming they would not nominate the small forward. Hawthorn said that their decision had been influenced in part by their late entry into this year's draft. Having traded heavily to procure Jaeger O'Meara from Gold Coast and Tom Mitchell from Sydney in this year's trade period, the Hawks don't have a selection in the draft until pick 88, a selection they obtained in a deal that moved five-time best and fairest Sam Mitchell to West Coast.

While the Crows have nominated Jarman, they aren't yet obligated to pick the 173cm goalsneak and have until November 18 to guarantee they will bid for Jarman. If the Crows decide to proceed, they have the right to claim a 20 per cent points discount off any club that bids for Jarman on draft night the following week in Sydney.The teenager is widely viewed as a late-round prospect in the coming draft. If no clubs bid, Adelaide could take Jarman with their final selection or have priority access to him as a rookie. Jarman was one of five possible father-son selections to be nominated by their prospective clubs on Monday. Another 20 possible academy selections were nominated by Brisbane, Gold Coast, Sydney and Greater Western Sydney. Collingwood nominated Callum Brown and Josh Daicos, both of whom are expected to attract bids at next month's draft. West Coast declared their interest in Jake Waterman, the son of former defender Chris, while Geelong nominated Sean Simpson's son, Sam. Jack Bowes (Gold Coast), Will Setterfield and Harry Perryman (GWS) headed the list of academy nominations. The Lions nominated Jacob Allison, Declan Watson, Jack Rolls, Nate Dennis and William Fletcher. Bowes, Brad Scheer, Josh Williams, Daniel Charlesworth, Jesse Esam, Nicholas Kempe, Curtis Marsden, Max Spencer and Shawn Watson were put forward by the Suns. The Swans nominated Jake Brown, Darcy Baron-Hay, Ryan Hebron, Callum McFadden, Ned Reinhard and Matthew Wilson, while the Giants nominated Setterfield, Perryman, Isaac Cumming, Sam Fisher, Ryan Garthwaite, Harrison Macreadie, Kobe Mutch, Zach Sproule and Lachlan Tiziani.
