I gave him a solid B vs. Greece. It was definitely the ultimate national grudge match, great effort on part of everyone. He went 10 pts 2 rebs, plus his usual defense and "little things."
Greece stopped scoring when Semih was on the floor; defense is his forte. As soon as Semih went off the floor, Schortsanidis (SP?) came in, and immediately got the ball in the low post, against Asik. Semih is a tough, strong dude. He is so much more fluent than Perk near the hoop that its isn't even funny.
But further out on the floor, he seemingly is responsible for the "Tony Allen Memorial Bonehead Play of the Game" every single game.

Two years from now, after Bryan Doo and Clifford Ray have a year or two to Woodshed him (the kid has a 'tude), I think Semih will be just fine.
