I had pick 6 and a future 2nd or 2nd to Carlton for Cerra, but can see SPS being put in and i think likely. SPS is worth a 3rd rounder.SPS is worth nothing. It should be pinned at the top of this thread it has been stated often enough.
No way do we send a pick back for 6 + a future 2nd. I would be disappointed with that return for Cerra.
