CHICAGO -- Nebraska's Bo Pelini isn't apologizing for his fiery demeanor on the sideline.
Heading into the Cornhuskers' first season in the Big Ten, Pelini said he isn't planning on changing the way he coaches his players, either.
In the Cornhuskers' final season in the Big 12 in 2010, Pelini was criticized for berating officials -- as well as Nebraska freshman quarterback Taylor Martinez -- during a 9-6 loss at Texas A&M.
Pelini said Friday that his relationship with Martinez is good and blamed the media for blowing the incident out of proportion.
"I raise my voice and discipline players and that's why we have discipline in our program," Pelini said. "We have this politically correct society where people say you can't raise your voice. I disagree."
After the loss at Texas A&M, in which the Cornhuskers were penalized 16 times for 145 yards, Pelini was whistled for unsportsmanlike conduct in the fourth quarter. Pelini also had a sideline exchange with Martinez, in which he poked the quarterback's chest and screamed at him.
Apparently, Pelini was upset that Martinez had used his cell phone to talk with his father in the locker room, a violation of team rules.
The next day, Nebraska chancellor Harvey Perlman said Pelini's behavior was "unfortunate."
"I've yelled at plenty of guys like that before and you see it on TV every week," Pelini said. "It's nothing personal. You can yell at a guy or discipline a guy and there's a trust between the player and coach."
Pelini said he won't ever apologize for disciplining his players.
"I don't run around yelling at my players all day," Pelini said. "But if somebody needs a talkin' to, I'm going to give them a talkin' to. Our players know there are expectations and it's not debatable. It's pretty black and white. If you asked our players, they'd tell you they don't want me to change."
Nebraska defensive tackle Jared Crick said Pelini's tirades are just part of who he is.
"The thing that happened at Texas A&M, we all know what happened and it might have been worse if we'd handled it," Crick said. "It's just who [Pelini] is. He's not yelling at you because it's personal. He's doing it because you're hurting your brothers or hurting the team. He wants to you to be the best player you can be."
