Here’s one from left field for you all:
Heat: Lowry/PJ(S&T)/Robinson/Herro (or picks/Yurt/etc

) for Kyrie/Harris
Nets: Kyrie for Lowry/Herro (or picks

)
76ers: Harris for PJ (S&T)/Robinson
This gets 76ers the piece they want, while clearing space and getting a shooter. Nets swap PGs for one that isn’t a problem internally & pick up asset(s) (picks/Yurt/etc or Herro).
Heat get two pieces that help the win-now movement and give more offence. Harris’ deal is hideous, but if he was paid half he’d be a steal and desirable. Next to Bam he’d be a pretty good fit.
We can then resign Dipo & Martin to round out the roster. Kyrie/Dipo/Jimmy/Harris/Bam plus Gabe/Strus/Martin/Jovic/Yurt on the bench.
