Gonna post an aspirational variation to my OP here, which makes financial sense for the parties, but is slightly more complicated (but better for the Cs) from a pick perspective:
BOS gets: Chris Andersen; POR 1st protected for selections 1-10 in 2018 (conveyable if POR conveys a 1st round pick to Denver in 2016), 1-8 in 2019 (conveyable if POR has conveyed a 1st round pick to Denver by 2017) and 1-6 in 2020; Heat 2023 1st.
POR gets: David Lee; Jarnell Stokes; 2016 Heat 2nd (from Cs); 2018 Heat 2nd
MIA gets: Cleveland 2016 2nd (from BOS).
Portland saves $8mil, Miami gets out of the Repeater Tax, Boston punts unneeded 2nds this year for future picks.
I'd just cut Andersen, btw.
