According to Ricky O'Donnell's latest mock, the Spurs would select Ngongba, a 6'11 big man with 'immaculate finishing touch, slick passing ability, and proven paint protection instincts.' This selection would give the Spurs two young players who can make plays around the basket and defend at a high level.
Ngongba, in his second year at Duke, has shown significant improvement with increased playing time. If the Spurs prioritize inside play and rim protection over shooting, Ngongba could be an intriguing fit at the No. 12 pick.
