Giddens will benefit from D league. Pruitt should start getting some minutes here and there, as long as the defense he showed in preseason is still present and that pretty outside shot he should get rotation time by the end of the year. IF he keeps the turnovers down, I don't see Sam back in anyway.
Walker I think can help the team THIS year, PP has any time off for injury I'd honestly like to see walker with the starters.
Now I know this won't happen but he has the size and attitude.
