Are you certain this is the case?
I recall reading an article saying that Port were looking to get a 2nd and 3rd round pick for Chaplin and Pearce.
I'm pretty sure this is the case. lets just say port lose 4-5 players to FA this year? does that mean they get 5 additional picks in this years national draft from the AFL? (the comp picks for FA can't be banked, and have to be used in the same year they are received). If this was the case - the first round of the draft could finish at pick 35!?
