Wisniewski, a 6-foot-3 275-pound guard from Pittsburgh (Pa.) Central Catholic, arrived in Chapel Hill late Friday night and spent most of the day touring the campus and football facilities.
"Oh, it was beautiful," said Wisniewski. "It has really nice facilities and trees everywhere."
Additionally, Wisniewski spent a good bit of his time talking to members of the academic department as well as members of the coaching staff. For the first time, he spoke in-depth with Weber, UNC's offensive line coach.
"He was talking about a lot of stuff that he does different like his philosophies," said Wisniewski. "I like him a lot."
The staff also discussed their recruiting situation, explaining Wisniewski's significance to their recruiting class despite the verbal commitments of other offensive linemen.
"They told me they just got a commitment from another Pittsburgh lineman, [Cameron Holland]," said Wisniewski. "It should be cool, I get to scrimmage [Holland] soon. They didn't say it would affect me, they told me I'm real important to them."
According to Wisniewski, other commitments won't affect him either come decision time.
Now, Wisniewski has unofficially visited each member of his final four with the exception of Boston College. He plans to make that visit before the summer lets out.
Wisniewski, who is currently vacationing with his family in Edisto (S.C.), says that things are still equal among his favorites, which also include Penn State and Michigan.
"I think, it's still the same top four – I still have them all about the same," said Wisniewski.
During his senior football season, Wisniewski plans to take official visits to each of his favorites to assist him in making a late December verbal commitment.
According to Scout.com, Wisniewski is the 10th ranked offensive line and 78th ranked prospect in the nation.
During his junior season at Pittsburgh (Pa.) Central Catholic, Wisniewski earned first team Class AAAA Associated Press All-State, Pittsburgh Tribune-Review "Terrific 25" and All-WPIAL honors for his play on the offensive line. On defense he recorded 64 tackles including ten for losses and six sacks.
