I have T-Mac on my team but I wanna get rid of him because of turnovers?

If you want to get rid of turnovers, I would look to trade Dwight Howard before I would trade T-Mac. If you are concerned about his troublesome back, then I can understand trading him away. To answer your question it depends if you want ists or not..PG will equal out your TO with their ists, but have the ball in their hands more, so they will turn it over more. See if you can get a guy like Antawn Jamison, or if you want multiple players Jason Kapono and Tayshaun Prince are very good in the TO department.
