Renfro was converted into a Safety, and like many rookie safeties, he was also used as a returner. He would lead the NFL in Returns and Return Yards and had seven picks. Renfro was also named to the Pro Bowl, and that would usher in a ten-year run of selections to that post-season honor. Renfro would lead the NFL in Interceptions with 10 in 1969 and had 52 in a career spent entirely with the Cowboys. Renfro was also a vital part of Dallas wins in Super Bowl VI and XII.
This was an outstanding career for someone who was not a Defensive Back in college!Renfro would be inducted into the Pro Football Hall of Fame in 1996, and the Cowboys Ring of Honor in 1981.
