"They just said that I would look good in Carolina Blue and that I had an offer from them," said Vaughn, a standout wing at New Hope (Minn.) Robbinsdale Cooper. "They told my coaches and then they told me.
"I was thankful to get an offer from such an elite school."
Williams and Davis had to make a quick postgame exit to return to Chapel Hill, as UNC plays host to Virginia at noon on Saturday, but the extent of the Tar Heel staff's interest level was clearly conveyed.
"They really didn't say too much becasue they had to go," Vaughn said. "We've been talking a lot more lately through text and on the phone. They are recruiting me pretty strong."
Vaughn did speak at length with Williams over the phone earlier this week.
"Rashad had a great conversation with Coach Williams a few days ago where Coach Williams compared him to Paul Pierce," a source close to the situation told Inside Carolina. "He really likes Rashad."
Friday marked the second time in as many months that Williams and Davis traveled to Minnesota to see Vaughn. The two UNC coaches attended a 35-point, 7-rebound outing on Jan. 5.
The 6-5 Vaughn, ranked the No. 2 shooting guard in the junior class and No. 13 overall, is also being recruited by Baylor, Kansas, Syracuse, Iowa State, Maryland, Kentucky, Louisville, Minnesota and Florida.
Vaughn is the fifth uncommitted 2014 prospect with a UNC scholarship offer. Wings Justin Jackson, Theo Pinson and Justise Winslow were offered late last summer, as was center Jahlil Okafor. Point guard Joel Berry accepted his offer three weeks ago.
The next step in Vaughn's UNC recruitment is a visit to Chapel Hill. That's in the works.
"Me and my family have to figure out a date," Vaughn said. "We are really going to try and get down there when they play Duke (on March 9)."
