Costner Quote: "My decision (to pick NC State) wasn't tough. I felt very comfortable with the players especially after my visit. I am also very comfortable with the coaches there. It's also the ACC, and it happened to be the closest school to home that I was really considering. I have family only a couple of hours away in Maryland. My family and I are very happy about the decision."
Sendek Quote: "Brandon is a tremendously skilled and versatile player who also has the advantage of being from a basketball family. He is a good passer and his ability to play both inside and on the perimeter fits perfectly with our style of play."
