Cal Ripken, Sr. never made it to the big show. He played in the minors for the Orioles farm system and eventually became a coach. He managed the Baltimore Orioles minor league team for 13 years and eventually went on to manage the Orioles on a couple occasions. Ripken, Sr. spent 36 years with Baltimore as either a player, scout, coach or manager. In 1987, he became the only person to have managed two of his sons (Billy and Cal) at the same time.
Junior's playing career was the complete opposite. He played for one team his entire career and broke Lou Gehrig's consecutive games played streak in 1995 (2,130). Cal did it with class, too. He revolutionized the shortstop position by being productive offensively and with his size, paving the way for guys like Alex Rodriguez and Derek Jeter. His legacy was solidified when he was inducted in the Hall of Fame in 2007.
