My best case scenario is that he either goes Houston or San Antonio
I don't hate either team (I respect the Spurs a ton too), but also that keeps him out of the East and also away from Philly and the Lakers. Likewise, either team w/Lebron beats GSW and likely "ends" their dynasty soon.
Now he could stay in Cleveland and I wouldn't mind either, although I'm still a little wary as they could package that #8 (and maybe Love) to acquire an all-star (like any of Lilliard, McCollum, Kemba, Beal, etc.) which could keep them in the mix. Boston would still be favored next year but they won't be clear-cut favorites unless Lebron simply leaves the East.
