California football player Ted Agu died Friday after collapsing during a training run with his teammates. He was 21.
"This is one of those tragedies that no one can understand and comprehend," an emotional coach Sonny Dykes said at a news conference.
"Ted was a very special young man. As a coach, you have the opportunity to be around a lot of special kids day in and day out. He was a special young man. He just had a passion and energy for life that's contagious. He will be deeply missed. Our players loved him dearly and he was a big part of our family."
