He may end up staying with Portland, who knows.
But there are a few teams who could use him.
If he doesn't mind coming off the bench, I think the Thunder, the Spurs and the Pacers could all use a guy like him, and the Heat as well (he loves James).
If he wants to start, I think his best option is Detroit. He may be able to start in Miami, granted, but it would be a small role. In Detroit he'd be the primary ball handler.
The Knicks could also use him.
He's a decent ball handler with a good 3pt shot.
