This season, you keep it how it is. You gotta keep Ray in the starting lineup, Tony off the bench, and keep their minutes how they are.
Next season though is a different story. Depending on how this season turns out will depend on alot obviously. But they need to take a serious look at the possibility of either not signing Ray back at all, or signing him for much less money and making him a 6th man.
Which then perhaps opens the door for TA in a starting role or signing another starting 2 guard.
