"It was getting down to the wire and I felt like I could make a decision. I felt like an early decision was better, rather than just waiting it out."
A versatile 6-10, 200-pound prospect, Henson is rated by Scout.com as the No. 6 power forward in the 2009 class and the No. 24 prospect overall.
"I really like the tradition and I really liked Coach [Roy] Williams," Henson said. "He was straight forward and he told me what I need to work on and where he sees me. I thought that was pretty cool for him to do that with me and we sat down and we had a nice little talk.
"I liked the whole coaching staff and Coach [Steve] Robinson. All those guys are great, too."
Henson is averaging 22 points, 12 rebounds and five blocks this season. He said the Tar Heels' up tempo style of play was also a key factor in his decision.
"I love the system and the way they run," he said. "That's what I like to do, so that's what I felt would fit me perfectly."
Though he said throughout the process that it wasn't a leading factor in his decision, Henson was born in Greensboro, N.C. and has relatives that live near the N.C./Virginia border
