One example of a star traded for a package was when Philly traded Iverson, who was 31 at the time, to the Nuggets they got 2 #1 picks in 2007 with Joe Smith and Andre Miller. 2 yrs later Iverson was gone. The two #1 picks turned into Jason Smith and Derrick Byars who was picked 42nd, the 76ers moved the 30th pick to portland for the 42nd pick and cash. Byars was released before the 2007 season started. Joe Smith played 54 games for Philly and was gone the next year. Only Andre Miller was of value he gave the 76ers 3 good yrs before leaving via free agency to sign with Portland.
Many times these packages don't turn out to be much, in the case of Iverson neither team got much out of it.
The best example of a deal like PG getting traded would be the Feb 22, 2011 trade that sent Carmello to the Knicks. Denver ended up getting Wilson Chandler, Ray Felton, Gallinari, Mozgov, a 2014 #1 and a pick swap in 2016 plus 2 2nd round picks, and Kosta Koufos from Minn, For Carmello and Chauncey Billups and some filler. The Knicks also sent Anthony Randolph and Eddie Curry to Minn.
Carmello was about 25 when that trade wen down.
