However, the most recent school to extend Hannon an offer – Northwestern – took the three-star recruit by surprise.
"To be honest, I was surprised I got the offer like I did because [offensive line coach Adam Cushing] told me that they don't offer linemen unless they actually see them first," Hannon said. "But with me they kind of pulled the trigger without seeing me first. So they extended the offer, and I was really happy about it."
With an offer in hand, Hannon is planning to make the trek to Chicago's North Shore either late this month or in early June, after completing his junior year of high school.
In addition to Northwestern, Arkansas, Duke, Houston, Illinois, Iowa State, Kansas, Kansas State, Missouri and Nebraska have offered Hannon a scholarship, and he said recently that Oklahoma could add itself to the list in the near future.
While Hannon is not yet sure which of the aforementioned teams he'll be suiting up for, he did confirm one future team he will be a part of outside of his high school team: the Under-19 USA football team.
"Actually, I just found out tonight," Hannon said. "It feels great. I'm just honored that I'll be able to showcase my talent among the best in the country."
The International Federation of American Football Under-19 World Championship, which is part of the World Football Festival, is scheduled for June 30 through July 7 in Austin, Texas, and it is expected to feature, from seed No. 1 to seed No. 8, the U.S., Canada, Japan, Panama, Austria, France, Sweden and American Samoa.
Hannon, however, is not likely to be intimidated by the international stage, as he noted that the Rockhurst football program – which has won nine Missouri state championships since 1971 and produced a litany of D-I players, including Illinois quarterback Nathan Scheelhaase – will be playing four consecutive state championship-caliber teams to kick off its 2012 campaign.
But a recruiting decision from Hannon is likely to have already been made by that point, the nation's No. 53-ranked tackle said.
"I was thinking this summer only because – this year especially – spots have kind of been filled up, and you never know if it's going to be there tomorrow," Hannon said. "If everything was perfect, I'd probably wait until the season so I could take [official visits] and everything, but it'll probably be sometime in the summer just due to the fact that I don't want my spot to be taken up."
Beyond Northwestern, Hannon said he is also planning on attending the offensive and defensive linemen camp at USC on June 9 and is considering an unofficial visit to Ohio State, as well as return trips to Arkansas and Nebraska.
"I want a place where I can contribute to the team and a place where the program is on the rise," the junior prospect said. "I think it has to be all-in-one package – I have to feel comfortable at the place I'm going to."
Meanwhile, with regard to Northwestern, Hannon said the coaching staff is recruiting him more as guard, which is fine by him.
"I have no problem with it at all," Hannon said. "Wherever I can play at, I'll play at. Even if they want me at center, I'll play center – I'm cool with it … Academics is already there, obviously, so we'll see how I feel coming out of the visit."
