Though rumoured to be sorted day one of the trade period, it appears St Kilda and Essendon's negotiations for Jake Carlisle may last until the final days of trading.
Essendon want pick 5 but St Kilda's list manager, Ameet Bains, says that the pick is not on offer.
"They want pick 5, which we are not willing to part with," Bains said on Monday.
"It's up to us to see what else is possible."
Earlier today, senior coach Alan Richardson stated Saints would only trade picks, not players, to get the young defender in the red, white and black.
It is unlikely that Essendon will settle for anything less than a first round draft pick in exchange for Carlisle.
There are opportunities for St Kilda to increase the number of first round picks they possess, if they are willing to trade pick 5 to another club.
Through the Patrick Dangerfield trade, Adelaide now own picks 9 and 13, which has been regarded as a potential option for St Kilda to break the deadlock.
Adelaide is to yet comment on these discussions.
In other trade news, it has been stated that Collingwood has shown interest in both out of favour forward Ahmed Saad and upcoming midfielder Blake Acres.
St Kilda is yet to comment on these rumours, though if true they would assist in St Kilda's efforts to secure Nathan Freeman if trade negotiations struggle.
Saad is out of contract and out of favour, spending most of 2015 with VFL affiliate side Sandringham.
Acres has signed a contract extension which will see him stay at the Saints until the end of 2017.
If a trade involving Acres was on the cards, both he St Kilda would have to mutually agree on a move.
