I cannot see Murray and Mudiay starting the year together as defensively that could be a nightmare. Mudiay and Harris need to continue to build off of last season. Murray and Barton handling the second unit would be a great compliment to Mudiay/Harris.
The general consensus about Murray is that he is going to make a career being a high scoring guard due to his ability to create space because of his mid and long range jumper and great court vision.
Time will tell if Coach Malone can adequately teach Murray to play defense.
