The Roos are noted to be open to parting with the prized pick this year, however the scenario may change should last year's No.1 pick in Jason Horne-Francis depart Arden Street before next Wednesday night's trade deadline.
The Giants are among the few clubs that hold a draft hand that might please the Roos, with News Corp suggesting the New South Wales side is pressing their case for Pick 1.
The Giants' hopes of hitting the top of the draft board come amid their interest in the aforementioned Cadman, whose stellar 2022 campaign with the Rebels and Vic Country has seen him bolt into contention for Pick 1.
North Melbourne are likely to bid on Brisbane father-son prospect Will Ashcroft atop the draft before turning their attention to a quartet of names, with Cadman the only non-midfielder in that shortened group.
George Wardlaw, Harry Sheezel and Elijah Tsatas are also in the top five mix and could be of interest to the Roos, however Cadman's position as the draft's best key forward falls as the most suitable selection for the Roos.
Should Horne-Francis depart and the Roos gain Pick 8, they may move for one of the three early midfielders and have their sights on Oakleigh tall forward Matt Jefferson with their second selection.
Jefferson, a more athletic forward, is in consideration for the top 10, while Cadman has emerged at the front of the key-forward queue after his 34 goals from 12 games for GWV in 2022.
