FRISCO, Texas (AP) Kansas running back Khalil Herbert still isn't comfortable talking publicly about his connection to the Florida school shooting five months after it happened.

Herbert attended Marjory Stoneman Douglas High School through his junior year before going elsewhere for his final football season. Despite the move, Herbert remained close to one of his coaches, Aaron Feis, also a security specialist who tried to shield students from bullets and was among the 17 killed in the Valentine's Day massacre.

"Coach Feis taught me a lot about the game," Herbert said Monday, the first of two Big 12 media days in the Dallas area. "Taught me to believe in myself and my abilities. He's a huge part of why I'm here right now. It's still tough to talk about."
