Of course, those walking down the hallway at East River High surely notice the hulking offensive lineman, a rising junior who won't go unnoticed much longer. He's sure to standout once spring football kicks in May 1, which the first-year Orange County school didn't have last year.
When he attends the Bishop Dullaghan Down and Dirty Lineman Camp at Stetson in June, the proverbial cat -- or lion, if you will -- will be out of the bag.
He says he's ready. Ready or not, before he knows it, recruiting coordinators and scouts will be flocking to East River to see the big, soft-spoken guy with the strong drawl.
"You take Max Lang over at Boone, at 6-4 or 6-5, 225 pounds," Kearney said of Lang, the 11th-ranked player in the Sentinel's Central Florida Super60. "Adam is four inches bigger and 100 pounds heavier."
Lang is actually closer to 290 now. Kearney worked with Lang at Boone High two years ago. But yes, you get the picture. Duckett is big, but that doesn't mean better than the person across the line of scrimmage.
"Being as big or bigger than some of the older players, you have to still adapt to that grade and quality of player," Duckett said.
That adaptation will come with time.
"Duckett's biggest problem right now is his inexperience on the football field," Kearney said. "He was literally too big to play pee-wee football, couldn't even play in Pop Warner.
"In ninth grade at Timber Creek he was so big that they just stuck him on the defensive line. He played like three games at Timber Creek, so last year was his first year of playing football from August until November. So he's got 10 games worth of football experience, basically. But he did a lot of great things for us last year."
Duckett weighs 320 pounds, but he doesn't look it. His frame is tone, his legs look nimble. He's somewhat of a mirage on the East River campus.
"I took him over to the University of Cincinnati game at South Florida and their offensive line was walking out and Adam was four inches taller than every one of their offensive linemen," East River assistant coach Marc Rankin said.
"And he can move," Kearney added. "He's got a 4.8 40 and he's strong as an ox. He's got quick feet. If we can get hinm to seal down, he can crush one whole side of a defensive line."
Big words, but this is a big guy. A one-of-a-kind specimen who Kearney can't wait to see on the field next season.
Duckett is coming to realize that he could make a nice career out of football, and even though he may still be a bit overwhelmed when considering his potential, he knows what lies ahead.
"It's a big goal to play college football and just a big privilege to be able to play high school football at a school like this," Duckett said. "As far as the future and playing college football and thinking about making a living playing football, going pro, that's just a dream."
It was an interesting year last season for the first-year school, which pulled players in from existing University and Timber Creek high schools. The Falcons went 1-9, but the victory was sweet. It came in the season finale against what has sort of become the school's rival in Lake Nona, which was also a first-year Orange County school last year.
"There were a lot of ups and downs but we worked hard every day in practice and kept at it and it all paid off in the last game against Lake Nona," Duckett said.
Now there are expectations. But Duckett and his teammates say they're ready. They better be. After this coming year, East River will jump from 4A to 6A, so this would be a good year to get things started.
