NBA Player Eric Williams -- HOMELESS SITUATION IS KARMA ... Says 'Basketball Wives' Co-Star

Former NBA player Eric Williams has no one to blame for his terrible situation but himself ... because "God doesn't like ugly" ... so says his former "Basketball Wives" co-star Tami Roman.

TMZ Sports broke the story ... Williams -- who played in the league for 12 seasons -- claims he's homeless and in dire financial straits after blowing the fortune he made as a professional athlete.

We reached out to Tami Roman -- who appeared on "BW: Miami" with Williams a few years ago -- and she told us that she understands his homeless situation "because I have been there, but clearly God doesn’t like ugly."

Tami adds, "Meanwhile, my girl Jen (Eric's ex-wife) is being a beauty enjoying her new life and loving her new life."

FYI -- Eric was a total a-hole to Jennifer Williams on the show back in the day, trashing her virtually every chance he got and even THROWING A DRINK IN HER FACE on one episode.

Clearly, Tami feels that his current situation is nothing but pure karma.
