The entire city of Houston is gonna shun Kenny Smith after watching this clip* ... 'cause the Jet tells TMZ Sports why LeBron should NOT join the Rockets in free agency this summer.
We spoke with Smith about reports claiming LBJ could bail on Cleveland for the Sixers, Lakers or Rockets this off-season ... and he says moving to H-Town would be unfair.
Smith says Bron Bron can keep his throne on the shores of Lake Erie and still compete for a ring every year ... 'cause he can just recruit players to Cleveland, instead of the other way around.
*We're kidding. Everyone loves the Jet.
Meanwhile, LeBron looked awfully comfortable and happy chillin' at his L.A. crib while in town to play the Clippers and the Lakers.
FYI, L.A. was a nice 70 degrees and sunny today. Cleveland was 32 and snowy.
Just sayin' ...
