At last reporting, it looks like Garnett, Pierce and Terry for Wallace, Humphries, Keith Bogans, Kris Joseph, Marshon Brooks, first-round picks in 2014, 2016, and 2018 (the latter two unprotected) and the right to swap picks in 2017.
Let's call that package A.
Now, here is package B. Both teams suddenly realize that the Nets also possess the expiring contract of the SF equivalent of Kris Humphries in terms of value and relevance to the Celtics' long-term plans. Let's call him Kris Humphries, Jr. or KHJ.
The Nets offer this alternative package, which we will call package B.
Garnett and Pierce for Kris Humphries, Kris Humphries Jr, Kris Joseph, Marshon Brooks, and first round picks in 2013, 2015, and 2017 with normal lottery protections. There are no pick-swapping rights involved. Assume the deal would be made before the draft and the Nets would select a player dictated by the Celtics.
So, effectively, the Celtics keep Jason Terry, get an expiring contract of a player who won't be a Celtic beyond this season instead of Wallace and Bogans, and down-grade the quality of their first-round picks by getting a 2013 instead of 2014 pick and protected 2015/2017 picks instead of unprotected 2016/2018 picks.
Do you prefer package A or package B and is your decision close?
