Charles Barkley was not always in love with the idea of playing at Auburn. In the upcoming SEC Network documentary "Bo, Barkley and The Big Hurt," the Auburn legend reveals he nearly transferred to Alabama after a brief falling out with coach Sonny Smith. The SEC Storied documentary will debut Aug. 21 at 7 p.m. CT. "I called the coaches at Alabama at the end of my sophomore year and told them I'm transferring to Alabama because I had just had enough," Barkley said. The documentary chronicles the Auburn careers of Barkley, Bo Jackson and Frank Thomas -- the trio who helped launch the Tigers into the public eye and lift the football, basketball and baseball programs into the national spotlight during their time on campus in the 1980s. Barkley, who believed he was destined to land at Gadsden State Community College out of Leeds (Ala.) High, discusses his relationship with Smith, his weight problems during his playing career and the state of Auburn athletics during the early 1980s. "I got on him really bad one day and he couldn't take it any more," Smith says in the documentary. "He just walked off the floor and quit." Barkley and Smith worked things out during a three-hour conversation, and the rest is history: Barkley stayed around for another season and went to the NBA to start a Hall of Fame career.
