San Antonio Spurs: Bruce Bowen27 of 30JEFF HAYNES/Getty ImagesWith a franchise that's had as much success as the San Antonio Spurs have had over the past three decades, there are going to be plenty of perfect-fit free-agent signings. He blossomed in San Antonio, becoming a reliable starter and epitomizing the three-and-D role before it was cool. 12 jersey was retired by the team in 2012, though he temporarily un-retired it in 2015 when team signed LaMarcus Aldridge. While Bowen turned out to be the best free-agent signing in franchise history, Aldridge is undoubtedly the biggest star to choose San Antonio in free agency. Aldridge played his role well, making a pair of All-NBA teams during his four years in San Antonio.
