Tester, I posted early this evening before Jason Quick broke the story of the teams from my source....
Taking it further to what I've been told is that Boston is in the lead because of the future 1st has less restrictions and that Boston is probably 2-3 years away from becoming a lottery team again.
Chicago is offering their own 1st round pick which is less desirable, but Portland is asking for Chicago's rights to Charlotte's 2012 1st round pick.
New York is less desirable of all the three teams involved with New York offering a first round pick in 2014 with a slew of restrictions (making it more like 2017). Now IF New York is offering Anthony Randolph for Rudy & Jeff Pendergraph, then you are talking about a good trade.
Anyway, I was told Boston is the front runner and that it will be a three team deal with Portland getting a young PG back.
$8.65M - Rudy Fernandez & Joel Przybilla to Boston
$7.08M - Rasheed Wallace ($6.32M retiring), Tony Gaffney & 2013 1st round pick to ?
$??.??M - {young PG} to Portland
