I think that this years Richmond 1st rounder after the the fs/nga etc picks is going to be pretty average along with this crop not (at this stage) as being rated very highly. Port are desperate for a tall kpd and i'm guessing that Bolta would not be on the table so not sure what could be advantagous for Port - saying that I don't want to lose SPP, his manic defensive play this year has been very very good.
Whilst this may sound silly to you its like me saying i'm guessing Marshall would not be on the table .
As another poster mentioned numerous times , Im not sure what you believe SPP is worth i wouldnt pay anymore for him than a pick between 20-30 and genuinely hope this trade does not happen.
