Former BYU running back Harvey Unga worked out for 20 NFL scouts on Thursday morning. Unga withdrew from BYU in the spring, citing an honor code violation. Weeks later, the school's administration announced he could not return to school until January of 2011 at the earliest. "No, not [bitter] at all," Unga said. "If I am bitter, that's the wrong thing to do. I made the mistake. I am a grown up, I am a man now. I signed the honor code when I got here. I had a violation....It is what it is. For me to be bitter, that's absolutely not the case." Unga revealed that his fiancee, former BYU women's basketball player Keilani Moeaki, gave birth to his son on the 4th of July in the Chicago area.
