“Trayvon, right now, is definitely one of our top hopes,” Harbour said. “He was the world champion indoor this year in the 60. Trayvon, if he’s on, he’s got a shot to win the gold medal. You’ve got to get there first, you’ve got to make that team, and that’s not a given. Our system is so tough, and you have to be on that day.”
