Hennessey, a 6-foot-2 210-pound athlete from Cleveland (Ohio) St. Ignatius, believes the Davis visit could seal the deal stating that "it's definitely a possibility" that he could verbally commit to Davis during the in-home visit Tuesday.
"[I like] the campus and the all the people and just how everything operates there – it's a lot like Cleveland," said Hennessey.
Outside of UNC, Hennessey doesn't possess any Division I-A scholarship offers. However, Navy is interested and could offer if Hennessey visits Annapolis.
Davis first became interested in Hennessey well before he decided to accept the head coach job in Chapel Hill.
"When Coach Davis got released from the [Cleveland] Browns, he came to a few of the Ignatius games and saw me," said Hennessey. "He got interested and once he got the job [at UNC] he got in touch with me."
This past weekend, Hennessey took his lone official visit to North Carolina where he was hosted by Chase Rice.
"It went very well," said Hennessey. "I went Saturday and got back today.
"They showed me the facilities, the school, I met with an academics adviser, and they just showed me a good time. I got to meet all the players. I got to meet all the coaches and spend some time with them, get to know them – start a relationship there."
Despite being an all-state selection at safety, North Carolina is recruiting Hennessey for linebacker. However, Hennessey played linebacker during his freshman, sophomore, and junior seasons, and his safety position was often utilized as an extra linebacker.
"Depending on what coverage we ran, I was run support or I was deep coverage," said Hennessey. "I came up in the block a lot acting like an extra linebacker."
During his senior year, Hennessey collected 135 tackles including two sacks, recorded two interceptions, and forced two fumbles.
