Ronald Glen "Big Baby" Davis (born January 1, 1986) is an American professional basketball player noted for his physical play, energetic bench contributions and the nickname "Big Baby." He played collegiately at LSU before entering the 2007 NBA draft. Selected 35th overall by the Seattle SuperSonics, he was traded on draft night and began his NBA career with the Boston Celtics, with whom he won the 2008 NBA championship. After his NBA tenure he continued to play professionally, including a period with the St. John's Edge and other teams documented in his professional profile.

Early life and college

Davis grew up in Louisiana and emerged as a productive frontcourt player in high school before enrolling at LSU. During his two seasons with the Tigers he developed a reputation as a capable interior scorer and rebounder. After his sophomore year he declared for the NBA draft, forgoing remaining college eligibility to pursue a professional career.

NBA draft and championship with Boston

In the 2007 draft Davis was selected in the second round and was traded to the Boston Celtics. As a rookie he earned minutes as a reserve, providing physical defense, offensive rebounding and energetic play that complemented the Celtics' rotation. He was a member of the Celtics' 2008 championship roster and is remembered for his contributions during that postseason run.

Later professional career

Following his years in Boston, Davis also had stints with the Orlando Magic and the Los Angeles Clippers. Injuries and fluctuations in conditioning affected his ability to secure a long-term starting role, and he subsequently continued his career in minor leagues and overseas. Among those later stops was a season with the St. John's Edge of the National Basketball League of Canada, as noted in his broader career profile and league overviews such as the NBA historical records.

Playing style and legacy

Davis primarily played power forward and, at times, center. He combined size and mobility with a soft touch around the rim, making him effective in short bursts off the bench where physicality and hustle were valuable. Coaches and teammates frequently praised his effort and the way he could change momentum in limited minutes. Over time, injuries and conditioning issues limited his longevity as a starter, but his role on a championship team and his distinctive personality have left a lasting impression on fans.
