DALLAS (AP) When Michael Bennett makes a tackle, he wants people to think of someone else.
The guy whose jersey he'll be wearing in the national championship game.
No. 53, Kosta Karageorge.
''This is bigger than just us,'' said Bennett, Ohio State's star defensive tackle. ''This is about a teammate we don't have with us anymore.''
Karageorge is believed to have taken his own life at the end of November, the walk-on nose tackle dying of a gunshot to the head after sending a message to his parents saying concussions had rattled his mind.
The death was a jarring blow to the Buckeyes. Most of the players had never lost a friend so close to their own age, their first real brush with mortality.
''They saw how precious the blessings in life are,'' coach Urban Meyer said, ''so don't miss one.''
Since Karageorge's body was found in a trash bin, a day after Ohio State beat rival Michigan, the Buckeyes have clearly been a team on a mission. They blew out Wisconsin 59-0 in the Big Ten championship game, claiming a spot in college football's first playoff. Then they stunned top-seeded Alabama 42-35 in the Sugar Bowl semifinal game.
Now, even as underdogs for the third game in a row, they see no reason why they can't bring a title back to Columbus.
''We definitely want to finish this season right for Kosta,'' said running back Ezekiel Elliott, who was a pallbearer at Karageorge's funeral. ''We know he's up there watching us. We know he's up there cheering us on.''
The investigation into Karageorge's death could reveal the dark side of college athletes, especially if it turns out that his brain was damaged by repeated concussions during three years as a college wrestler. The 22-year-old senior joined the football team in August, readily taking on the thankless duties of the scout team, playing a role on the opposing team to get the starters ready each week.
Karageorge never played in a game, but he won over many of his new teammates with his love of practice and exuberant personality.
That's what the Buckeyes (13-1) were determined to remember as they prepared for Monday night's championship game against second-seeded Oregon (13-1).
''He grew so close to us, especially those of us in the D-line room,'' said Joey Bosa, another star member of the Ohio State defensive front. ''He just had such a crazy personality. He was always telling crazy stories. They would have been almost unbelievable if anyone else had told them. But when Kosta told them, you were like, `Damn, Kosta, you're crazy.' He was such a cool dude.''
Bennett and Elliott will be among those honoring their late teammate in the title game.
For the third game in a row, Bennett will wear Karageorge's number instead of his own No. 63. Elliott plans to again wear a small white towel tucked into the front of his pants, with the words ''RIP Kosta'' written in black marker.
''I wear the number because I want people, when they see me, I want them to think about Kosta,'' Bennett said.
When asked about the impact of Karageorge's death on his team, Meyer was quick to point out that he hasn't tried to use tragedy as a motivational tool. He certainly doesn't mind his players honoring a friend in their own way, but he doesn't want to make it more than that.
In the grand of scheme of things, this is just a football game.
That was a young man's life.
''I've got to be careful. We're talking about a family here,'' Meyer said. ''If you're saying that's why we've been winning games, that would be superficial. It has strengthened an already strong relationship to the point where, I don't want to say we're inseparable, but I saw extreme growth, more closeness. But I never want to say that's why we're winning games.''
Sure, if he's holding the trophy late Monday night, he'll probably look toward the roof of AT&T Stadium and give a wink to his friend.
But win or lose, this season will stay with him forever because of who wasn't there at the end.
''Kosta was such as unselfish guy. He loved his team and loved these guys,'' Bennett said. ''Our biggest thing is: Just don't let him be forgotten.''
