Hypothetical:
IF- This is a huge huge huge if- the rumours are true in regards to getting a top 5 pick a fairish deal may look like:
GWS: In-Mumford, swans first
Out- Mid first round compo (9, 10)
Melb: In- Parker, mid first round compo (9, 10)
Out- Pick 2
Swans: In- Pick 2
Out- Mumford, Parker, pick 15
Probably a realistic trade considering situation with Mumford and GWS
