The Lead As the Broncos' rookie class take the field on Friday, most of the limited media spectators will train their eyes on the cornerback group to get a glimpse of the team's first draft pick, Pat Surtain II, in action. Not far from him, though, should be a little-known college free agent out of North Carolina A&T who brings a lineage perhaps even more impressive than that of Surtain and his Pro Bowl father. Franklin McCain III goes by "Mac," but his full name shows the clear connection to a man who helped change the course of history in America as one of the "Greensboro Four."
