Though highly unlikely for Batum to drop to the Spurs, recent Mock Drafts have Batum falling to the late 20's. With that being said, the Spurs could draft Batum, but if they do, expect him to be stashed over seas in France.
Height -- 6' 8"
Weight -- 214 lbs
He will more than likely play the NBA SF position but he comes raw. He needs to bulk up seeing how current NBA players at that spot are physical -- see Melo.
Strengths -- Young and athletic. Just what the Spurs need. He can finish at the rim, a good defender and has an outstanding wingspan. He can score which is also what the Spurs need; someone with offensive punch.
Weaknesses -- A project and if the Spurs draft him, he will be stashed away in France to develop. There is questions about his toughness and his shooting touch. He does need to be more aggressive when out on the floor.
Why the Spurs will take him? Again, he is young and athletic!
