What is Grant supposed to do. He is sticking up for his teammate. Short of coming into the stands and trying to fight someone, I think he was trying to defuse the situation and make it not as bad.
I understand the situation, because I have yelled before and had a players parents nearby. You have to understand as well that parents don't think rationally. It is their child, they are going to come back no matter what is said.
Also, Grant is a senior who has been the most consistent player on defense for four years and played through injury, and has been an All- Sunbelt level player. So he won't be at a Juco. II think he was trying to stick up for his teammate more than anything. It was just a terrible night.
