An ACL tear forced him to miss his entire senior season on the gridiron.
The Braves picked him in the eighth-round in the 2010 draft, the same year they selected Andrelton Simmons, Evan Gattis, Joey Terdoslavich and Todd Cunningham, all of whom played in the big leagues last season.
Professional baseball didn't work out quite so well for Fleming, who played parts of three seasons in the Braves' system, but never passed the Low-A level. Fleming hit .244 with five homers and 52 RBI in 512 career at-bats in the minors. He also stole 15 bases.
"He's coming to college for the first-time, so I'm excited about him," said Dabo Swinney. "Good athlete, big, strong guy."
Swinney isn't certain as to what position the 22-year-old Fleming will play at Clemson. He could be used at running back or as a tight end/H-back, the position that's known as the 3-back in the hurry-up, no-huddle offense.
"I'm really anxious to see him," Swinney said. "This guy is like 235 pounds. I mean, he was drafted as a centerfielder. That's where he played. I don't think the Braves would draft a centerfielder that can't run, especially in the eighth-round."
Fleming was one of the freshmen to enroll at Clemson last week.
"We know he's a good athlete. I'm anxious to see him," Swinney said. "He might be a guy who fills a dual role. Until I see him in pads, it's hard for me to evaluate that."
The role could be similar to the one Darrell Smith occupied during his last couple of seasons at Clemson. In the past, Swinney has said that they will not recruit players to be used specifically as a lead blocker.
"Darrell was a guy who was a little bit of a throwback for us, a guy who was here as we transitioned systems, just such a good player [and] such a valuable guy," Swinney said. "We had to carve out a niche for him. As we move forward it's more of the tight ends for us. Those are the guy who will have to fill that role."
According to Fleming's milb.com profile, which hasn't been updated since he was released by the Braves organization in 2012, Fleming is 6-foot-1, 185 pounds. But he played at over 210 pounds in high school.
