Green, who plays high school ball for Tim Cluess' St. Mary's talent-stacked team in Manhasset, N.Y., played with Charles during the summer.
"Danny is a versatile player who does a lot of good things in many areas of the game," Charles said. "Coaches recognize that. He can play several positions."
Charles said the in home visit with North Carolina head coach Roy Williams convinced Green and his family to join the Tar Heel family.
"Roy told me that if Danny committed to them now that he would tell Martell Webster they were no longer recruiting him," Charles said. "So when he said that it convinced me."
It was probably an easier decision for UNC than most people believe. Webster, a terrific athlete, has one eye on college and one eye on the NBA. Green will likely be a four-year player for North Carolina and could end up being a very productive player for Roy Williams.
Green, 6-foot-5, is a good passer who can knock down the jumper. He also has decent hands and finds a way to get into the passing lanes for steals.
"Roy told Danny that he is going to have a chance to get some minutes," Charles said. "When that happens is up to Danny. But they told Danny he would have a chance."
Green is a big enough guard who can create some physical mismatches for opponents. He is also a much better athlete than most give him credit for.
"He'll get his opportunity," Charles said. "I was very impressed with Coach Williams' sincerity and honesty."
