Let me inform you here - an altercation involves more than one person. In the 2nd quarter, there was Elson dunking and then Elson sitting on the floor. No Phoenix player anywhere in sight saying anything to him. No altercation.
Stoudemire left the bench rushing the middle of the court with a pissed look on his face, probably screaming obscenities. Duncan stood up to celebrate the dunk, saw Elson fall, and took a step on the court to see if he was ok. No anger, no obscenities, no altercation to rush to.
Get It? Stu Jackson did. He had a full night and a full day to review it and saw it from every possible angle, more than any of us. Give it a rest already.
