Any trade we do for a point has to be for a point that is better than Mo because it will be a long term solution and then Mo decides during the of-season whether he will re-sign to come off the bench (again, which he didn't like) or go elsewhere.
I am of the mindset to use who we have unless we can get a truly great younger point guard. Why trade value for other veterans when we already have veterans? Sure, they aren't amazing, but they know the offence and the less they shoot, the more our 'core' group gets to put up shots. (Then again, that raises their value....)
