Michael Carter-Williams is 22 years old. He has been anointed the leader of the Sixers because he is the point guard and is very talented. Being a leader comes naturally to some, others grow into the role. Coach Brett Brown says Michael Carter-Williams has a long ways to go -- as does this Sixers team -- but he has his starting point guard’s back. The Sixers' defense was lacking in the fourth quarter against Oklahoma City, Tuesday night. Perry Jones, the Thunder’s starting shooting guard, played seven minutes, but no other Thunder starter played the final 12 minutes. Still, the Thunder shot 61 percent from the field. At one point Brown called Carter-Williams over to the sideline during a stoppage in play, clearly upset with the Sixers' poor defense. Carter-Williams looked agitated that he had to have this discussion and before too long the body language of both men was of two people in an argument. It happens, but given where MCW is in his career -- namely the infancy stage -- listening in learning moments is a must. The rookie is an extension of the coach and must set an example to his teammates with his play as well as his composure. In this case, a lack of composure was shown on MCW’s part. “The deal is you are going to guard,” Brown explained of what upset him. “And you are going to keep the game in front of you, and if you don’t then we don’t have much." Brown said his conversation with Carter-Williams was productive.
