"Clearly, this was deliberate to hurt him, and you succeeded," Weld County District Judge Marcelo Kopcow told Cozad as he announced the sentence.

"The goal is to not ruin your life," Kopcow said. "I would like you to succeed in your life."

Prosecutors said Cozad ambushed starting punter Rafael Mendoza on the night of Sept. 11, 2006. Mendoza was left with a deep gash in his kicking leg but later returned to the team.

Mendoza was the punter for Northern Colorado in its game against Hawaii at Aloha Stadium. He punted seven times, averaging 44.7 yards as Hawaii won, 63-6.

Cozad was convicted in August of second-degree assault but acquitted of the more serious charge of attempted first-degree murder.

The 22-year-old Cozad, of Wheatland, Wyo., faced up to 16 years in prison on the assault conviction.

He spoke briefly today, thanking family and friends for their support and then offering an apology.

"I am very sorry to everyone for any pain and suffering you've endured. My hopes and prayers are to Mr. Mendoza and his family that they don't suffer anymore as a result of this ordeal," he said.

At the trial, Mendoza testified he could not see who attacked him in the dimly lighted parking lot. The assailant was dressed in black from head to toe and had a hood cinched up so only the eyes were visible.

Defense attorney Joseph Gavaldon had argued it was another university student who stabbed Mendoza, not Cozad.

Before Cozad was sentenced, prosecutors called on four people to make statements, including Mendoza and his mother, Florence.

Rafael Mendoza said he was convinced Cozad wanted to kill him.

"Even though he wasn't convicted of it, his intentions were clear," Mendoza said, fighting tears. "I'll never forget that. I've spent long nights since then waking up in a cold sweat, having nightmares, thinking I was going through that again."

Mendoza's mother asked Kopcow to give Cozad the maximum sentence.

"No matter how much time you give Mitch, it won't be enough," she said. "I don't believe he'll ever change. I don't know him as well as I thought. I'm suggesting you give him as much time as possible. I've been in fear way too long."

Cozad's fiance, Michelle Weydert, wept as he was brought into the courtroom and blinked back tears after he made his statement.
