'Yarbrough was an undrafted free agent and, at 24 years old, is on his second NFL team. In college, he was a highly productive pass-rusher. At Wyoming, he registered 39.5 tackles for loss and 21.5 sacks in his four-year career. While he was buried on a talented pass-rushing unit in Denver before coming to Buffalo, Yarbrough has the requisite athleticism to become a useful edge-defender in the NFL.'
