Oklahoma State senior defensive lineman Trey Carter (99) gets pressure on Oklahoma quarterback Kyler Murray.

Whether it’s his goofy nature that teammates know him for or his growth on the gridiron or his poetry writing, Trey Carter has left a legacy at Oklahoma State.

His legacy as a Cowboy is coming to an end. Carter and the remaining seniors on this year’s OSU football squad have two, possibly three, games left on the collegiate slate, depending on whether or not the Cowboys (5-5) qualify for a bowl game.

Carter and his senior class will leave their final legacy at Boone Pickens Stadium at 2:30 p.m. Saturday when OSU hosts No. 9 West Virginia. The senior day celebration will honor a large number of Cowboys before the final home game of the season.

The 6-foot-3, 300-pound senior from Dallas, who grew up in Louisiana is excited for the pre-game ceremony and the chance for a second-consecutive, top-10 home victory.

“It feels good. It feels awesome,” Carter said. “One last ride. One last ride in this stadium. All of the hard work we’ve put in to get to this point. I’m excited about it.”

Carter is hoping to have a large number of family members in town Saturday for his final home game. Part of that contingent could be his 15 – yes 15 – sisters.

Carter said it will be a chance for a lot of his family to see him play in person one last time. It’s that family that’s made him the man he’s become, especially his mother.

“When you’ve got 15 sisters and you’re the only boy, your mom kind of looks at you like the baby boy, so you become a mama’s boy,” Carter said. “So, yeah, I’m kind of close to my mom. I talked to her about everything, even football. Sometimes she doesn’t know certain things, but I’d still be trying to talk to her. … Yeah, I’m close to my mom. She’s my best friend.”

Carter also talked about how his 15 sisters have shaped him into who he’s become.

“You get sensitive in certain ways,” Carter said. “I had to outgrow that, because when I came here, I was a little sensitive to certain things. When you grow up with girls like that, you get sensitive in ways, but I toughened up.”

On Tuesday, Carter talked about his growth – on and off the field – at OSU. A big portion of that revolved around his growth from when he came to the Stillwater campus in 2014 until present day.

When asked about how he’s a different person now than he was during the 2014 fall, Carter chuckled a bit.

“Yeah, I have changed a lot,” Carter said. “Y’all have seen me in those TV shows with me and Ramon Richards and everything. Dealing with that type of stuff – the comedy and everything – I kind of grew up from that.”

Growing up and maturing – like most college students – was a big thing for Carter. He admitted it, as did his fellow defensive lineman Jordan Brailford, who came to OSU at the same time. Brailford is technically a redshirt junior because of being granted an extra year of eligibility due to a medical redshirt, but they both came to OSU in 2014.

In fact, they lived together, too, which prompted Brailford to laugh and share a story or two about his time with Carter.

“It’s an amazing thing. He definitely had his difficulties here,” Brailford said. “He actually got us kicked out of our first apartment together. We had to actually move to another apartment. He’s matured a lot. He was real childish coming in, but he’s grown up so much. He’s still a goofy guy, but you can see he’s matured and got his degree. He’ just making the right decisions.”

Brailford, who isn’t sure if he’ll participate in the senior day festivities, too, before possibly turning pro, continued telling stories about Carter. While joking about his younger days, he talked about how Carter has grown as a person since arriving on campus.

“I think his decision-making skills have gotten a lot better,” Brailford said. “One semester, he went through about five or six pets. I think he’s had his dog now for about a year, so he’s making progress.”

According to Brailford, Carter has owned two dogs, a scorpion, a tarantula, a snake, a gerbil and a lizard. Those were all of the animals he recalled Carter owning while they lived together.

After all of the ribbing, Brailford was serious about Carter’s growth during his four-plus years in Stillwater.

“He’s had his close calls,” Brailford said. “It’s no secret. Deep down he’s a good guy, so all of that is just being young and being from a different area. It’s all good.”

On the field, Carter has grown, too. He redshirted the 2014 season after coming to OSU as a four-star recruit by Scout.com. In 2015, he saw action in only one game, recording a single tackle.

“Frustration,” Carter said. “When you first come in as a freshman, you don’t know what’s going on. You’re just going for the ride, and looking at the older guys to see what they’re doing. … It’s kind of hard being a football player with your academics and stuff like that, so you’ve got to be manageable with your time. There is a lot of frustration that goes on. But now that I’m older, I know what to do now. That’s what I tell the younger guys.”
