I've given this too much thought...
Here's our new best case scenario.... get ready for this...
Miami re-signs Bosh, Bron and Wade.
This means LeBron doesn't go to Cleveland to form a superteam with Kevin Love. That means Bosh doesn't go to Houston to form a superteam. That means Boston still has a fighting chance at getting Kevin Love.
With LeBron off the table, the Cavs go to a backup plan of Ariza/Deng/whatever. Love will not re-sign in Cleveland without Bron there, so that ensures they don't include Andrew Wiggins in an offer.
Unless GOlden State jumps in again, that leaves Boston with a realistic shot of bringing in Kevin Love... and perhaps if we do that, we might also have the ability to work out a sign-and-trade for Melo. Rondo + Melo + Love would have a shot in the East.
It sounds counter-intuitive rooting for Miami to keep it together, but LeBron + Kyrie + Love would rule the league for a decade...
