A few thoughts....
Sydney is the fairest trading team in the history of the AFL. Unlike Essendon and Hawthorn we always take the interests of other clubs or unrequired players into account.
Example 1 - We gave Sean Dempster to St. Kilda for NOTHING!!!! Why? To be nice to him. Rather than put him on the open market where he was worth a second round pick we sent him to a team/coach where he would be a 22 player and under a coach he liked. (threw him in with Schneider trade)
Example 2 - We gave Scott Stevens to Adelaide for NOTHING!!!! (well a pick we didn't want to use)....see above.
Example 3 - We gave Essendon pick 19 for Ted Richards when he was on the cusp of being de-listed. Bombers thought all their Christmas' had come at once. They got Courtney Dempsey

Example 4 - We gave Melbourne Pick 15 for their 3rd string ruckman (Darren Jolly)...they thought all their Christmas' had come at once. We got 5 years years of Jolly and on-traded his pick for Lewis Jetta.....Melbourne got Lynden Dunn
Example 5 - We gave St.Kilda picks 13 and 17 and 45 for Hall (Dal Santo, James Kelly (Geelong) and Trent Knobel)
Now let's get real about the value of some of our players. If Luke Parker were in the draft every single team would take him in the top 10.... Examples of recent similar players taken 5-10 who have made it....Cunnington, Polec, Conca, Melksham, Heppel, Myers, J. Selwood, Armitage, Ziebell. And then there are the ones who don't make it. Parker is 19 FFS in only his second year. It is likely that at the end of their careers on Selwood would be above him. There is no way in the world that any club would punt on an 18 year draftee inside mid instead of having Parker who is a dead-set certainty. Had his jaw broken in round one...played on. Came back in 2 weeks to get 4 Brownlow votes before breaking collarbone.....came back in 6 weeks to be a premiership player.
Not that I'm offering him for trade - but at least try and understand his value.
Jed Lamb is not a spud - he is a very, very talented Stevie J type...but quicker....several BOGs late this year after overcoming injuries.
Tommy Walsh is not a spud...he's coming along very nicely.....kicking plenty of goals in 2nds and would be getting a clear run at a lesser club.
Heath Grundy is only a year older than Tippett. 101 kg key defender who was in the calculations of many, many commentators during All-Australian discussions (you don't have SEN in Adelaide but they sometimes discuss players from outside Adelaide). Considering that Rutten is nearly dead and Shaw and Talia are practically teenagers, I'd say that he has more than passing currency.
Of course who you would really want is Rohan or Jetta

- Um, sorry, pass.
BTW did you know Roos offered Richmond picks 6 and 14 for pick 3 in that draft? That's how much he wanted Dustin Martin...would have swapped Rohan and Jetta for him!!!
