Having played the position since fourth grade, Sullivan feels experience is a big reason why he's so successful.
"I have been playing center since fourth grade," he said. "My freshman and sophomore years, I played offensive tackle but I've pretty much always played center. I've really gotten to know how to play the position."
At 6-foot-3 and 270 pounds as a freshman, Sullivan said it's a much different frame these days.
"It's a much different 6-4, 280 these days," he said. "That's for sure."
The standout offensive lineman, who will turn 17 a week from today, carries a 3.3 GPA inside the classroom to go with a 1250 SAT score. In addition to football, Sullivan also wrestles, working on his foot work and agility.
With scholarship offers from programs from all across the country, Sullivan is starting to focus on narrowing things down.
"I have it narrowed down to a top five," he said. "They are North Carolina, Notre Dame, Michigan, Boston College, and Miami. I've already visited Boston College and North Carolina, and I leave this weekend to check out Notre Dame and Michigan. I'll probably check out Miami for an official visit."
With scholarship offers from all of his current favorites, Sullivan talked more about the Hurricanes.
"I was fired up to hear from Coach Kehoe at Miami in the spring," he said. "He said they really liked me, then sent me a scholarship offer in the mail. Miami was obviously the best team last year and I don't see them slipping anytime soon. They bring in a top recruiting class every year and I can see them continuing to win more national championships."
Sullivan said he hasn't attended any summer camps this year, as he's been home working out with his teammates.
"Our biggest goal is to win the state championship," he said. "It's a whole team thing to me and we all have the same goal."
