I know Isaiah Thomas is trying to be humble and has said he'd accept any role on an NBA team, but I don't think any of his tweets about his NBA status help at all. Many have called it "begging," but that's insulting to Isaiah. He's just a man who loves the game of basketball and believes in his heart he still belongs in the NBA. And that love of the game and confidence is what helped him reach the peak of the NBA.
The Lakers aren't going to sign Isaiah. They had him once already and moved on.
