FWIW I think the below trades are possible and take into account what we've heard out of the clubs involved.
Shai and 20 - For 10,11 and 30
Rioli, 51 and 61 - For 6 and 29
Even not allowing for Baker or other pick trades, it leaves us with: 1, 6, 10, 11, 24, 29, 30, 70 and 76. The important thing with the later 2, is both will come in significantly with the picks to disappear from the draft due to bids on Ashcroft, Lombard, Kako and Marshall. Not even allowing for the Campo twins, which would mean if we want we could match on
Baker we should get a pick somewhere between 12-18 from West Coast or Freo, or as mooted, a trade up to 3 which I'd prefer personally.
If WC did 3 for Bakes and 11 (not sure they would) but if they did that would leave us with a ripping hand. Some would say we came out short changed, but overall trading would have been good, maintained relationships with clubs when over the next few years we are more likely to be the aggressors in trades and hands us an almighty hand for the draft.
Probably 4-5 picks in the top 20 (with most of those in the top 10), then a couple of later picks for sliders in the 20's and finally keep the last 2 if we want our NGA kid basically for junk at the end of the draft.
