From the Zach Lowe LeBron piece, I thought the Phoenix option was really intriguing. Bledsoe, Dragic, and LeBron would be an absolute terror running Hornacek's up-tempo transition game.
But I really don't think LeBron is going anywhere because of the whole not wanting to be seen as a mercenary thing. Going to Cleveland would be okay in that regard, but I can't see him playing for Dan Gilbert and a franchise that doesn't have their act together.

Phoenix would have enough space to bring in Pau and a mid-level exception. Plus they have several draft picks this year.
