"The longer off-season helps us to bond, get the kinks out from last year and just gear up for next season stronger and faster. We're really working on fixing our offense and having a better core defense. We're just working on ourselves to get better for next year," he said.
In addition to training in the weight room and on the field, the Terriers also put in time in the film room.
"We watch a lot of film and we have certain days, classes, where we go over our technique and watch film from the opposing team we're playing. I've learned a lot; it's to the point where I don't really need to study my book because I'm in there and understand, can read and react," he said.
As he enters his final season as a Terrier, Charles is really trying to put in extra effort and serve as an example for the underclassmen.
"I try to be a leader in everything I do, be the strongest and set an example. It's the little things that you do; I'm here for the team and I want to lead them the right way," he said.
Charles previously played on both sides of the ball, but really feels like he shines best at middle linebacker.
"I've played offense before, but now I'm strictly defense. I think linebacker is where I'll stay for college. It's the thing I love to do; I love to hit people. I'm really aggressive and linebacker is just the best position for it," he said.
Charles might not have much height on him, but the 5'9", 200 lb. linebacker makes up for it in strength.
"The strength and power I have as a linebacker is probably my best strength at the position. I can make plays. I'm a core person on defense," he said.
Aside from working with his team, Charles also has a few things he personally is working on improving over the next few months.
"I'm working on my skill and critiquing my techniques. I want to become a better player overall and just help the team out the best way I can," he said.
Recruiting has been a bit slow thus far, but Charles isn't letting that get him down and is putting in effort to get his name out.
"I haven't had much contact with schools yet. I've sent some film out, but I'm working on getting my information out there. I'm starting off by looking at closer schools, like Arizona State, San Diego State. Wherever I can get a full ride, that's where I'll go," he said.
For now, Charles thinks he might want to stay in the West.
"I'd like to stay close to home; I have my mom and my little siblings, so I'd like to help out, and that's really my main goal, to get my education. Football is my ticket but my main goal is to be a technical engineer," he said.
