Sylla, who is expected to report to campus this summer after playing this past season at Stoneridge, a prep school in Tarzana, Calif., is from Paris, France.
Auburn coach Jeff Lebo says, "We think Boubacar has a tremendous body, and he has not been playing basketball for a long time. He has great size and terrific hands.
"He has a ways to go to get polished, but he is big and physical," Lebo says. "At 7 feet, 275 pounds, he has a frame, but he will have an adjustment to make in college. He'll be a better college player than in prep school because of the game and will be able to bang a little bit. He is a good passer and can shoot a 15-foot jumper."
Sylla played on a team loaded with college prospects and averaged just 2.4 points and 2.8 rebounds last season. However, his potential attracted attention from Division I programs from coast to coast. He is one of six players on the team who signed with Division I programs. Ibrahima Thomas signed with Oklahoma State, Mamadou Diarra signed with Southern Cal, Charles Boozer signed with Iowa State, Howard Little signed with Valparaiso and Mychel Thompson chose Pepperdine.
Scout.com ranks him as a three star prospect and rates him the No. 27 center prospect in this season's signee class. Scout.com basketball recruiting analyst Dave Telep says, "Sylla is a space-eater in the paint and you can't find size like that in the spring period."
