Chances are that Sanikidze was probably injured, per usual. Otherwise, it doesn't make sense for him not to play in summer league. The Spurs even invited freakin' Sergei Karaulov twice to summer league. Surely they would invite Sanikidze if he were available.
The only other thing I can think of is he may have upped his smoke or alcohol consumption to rates not permissible by the Spurs. I know I've joked about it in the past but when the Spurs drafted him, he was a clean cut kid. After he got drafted, he went Rastafarian for some reason. Hopefully I'm totally off base but bro has changed a lot in only a couple years . . .

At the very least, someone introduced him to the sun.

Solid D, I'll see what I can dig up. Thanks for the links.
