The 5-foot-11, 175-pound quarterback is coming off a banner junior season when he passed for 1,400 yards and 10 touchdowns and also rushed for 500 yards
"I had a pretty good season, I thought," he said. "I should show improvement for this year. We've got outstanding players back."
Chamberlin entered this season as a junior starting quarterback, a far different scenario as he started out this year.
"I feel more confident coming into this season," he said. "We do a lot of straight drop back formations or the rollout. They're both unique. I probably feel more comfortable with the straight drop back because I've done it more."
Chamberlin is looking at more passing opportunities with Trenton's offense this year.
"This year, I think we'll be about 50-50," he said. "Last year, we were about 70 percent rushing and 30 percent passing. We've changed our offense a little this year. We have the personnel to do it."
But Chamberlin expects to see more defensive back coverage against him during the year.
"We'll have to make sure our running game is going so we can open up the passing," Chamberlin said.
The Trenton quarterback has played his position for six years.
"One year I was put into the position. I did a good job at it and I kept going," Chamberlin said.
Chamberlin expects to play college football, perhaps at a Mid-American school, although he's also not counting out the possibility of a Division II or III career.
"I've gone to camps and have talked to some coaches about it," he said. "I probably stated thinking about a college career after my high school freshman and sophomore years."
Chamberlin is hoping Trenton can be a strong playoff contender.
"We have 21 seniors back from last year," he said. "We're expecting more this year."
