Looks like the Rioli trade is being dictated by Collingwood and the hold up with Noble trade. Pies stupid wanting Pick 13 as do we but Suns want both Noble and Rioli.
What will likely happen:
Pies need to accept Pick 23 for Noble.
Blues trade for Pick 13. They give up future first and some late picks for GC.
GC trade Pick 6 and Carlton future first for Rioli. With 6, 23 and 13 gone. We trade some late picks to GC.
That ruins the pipedream of 6 and 13. But looks less likely.
