Long before he put the final exclamation point on his 13-year career in orange-squeezed Super Bowl V glory, Billy Ray Smith Sr. arrived in Charm City as a seasoned, battle-tested interior force. Drafted out of Arkansas in 1957, the Augusta native spent his early seasons with the Rams and Steelers before joining the Baltimore Colts in 1961. Smith instantly plugged into the defensive line rotation, bringing relentless leverage, technique, and an unrelenting work ethic that earned him the fond nickname "Rabbit"—a nod to his surprising quickness off the snap for a 250-pound defensive tackle.

Smith’s greatest asset was his rock-solid adherence to defensive fundamentals and unshakeable locker room presence. As a multi-year defensive captain under head coaches Don Shula and Don McCafferty, he anchored the interior alongside Bubba Smith and Fred Miller, establishing a stout front that neutralized opposing ground attacks. His individual peak arrived during the historic 1968 campaign, where he earned Second-Team AP All-Pro honors while helping power Baltimore's dominant defense to the 1968 NFL Championship title.

His career reached a storybook conclusion in 1970. Operating as the heart and soul of the defense at age 35, Smith helped guide the Colts through a gritty playoff run that culminated in Super Bowl V against the Dallas Cowboys. In a hard-hitting 16–13 victory, Smith’s interior wall held firm, securing the franchise's first Super Bowl ring and providing the veteran captain with a perfect fairy-tale exit from professional football.

Durable and steady across a decade for the Shoe, Smith appeared in 133 regular-season games for Baltimore, serving as a trusted leader through one of the most successful eras in team history. Retiring immediately after that Super Bowl V victory, Smith left the game as a two-time champion who set the benchmark for professionalism and defensive line play in Baltimore.  He recorded 69.5 sacks in Baltimore.
