What happened in Belgrade? Didn't watched game, so, I had to check twice when I saw that Milano won game. After all, 4 wins after 10 rounds isn't that bad result for them, considering how awful this team sometimes looks.
Fenerbahche showed elite defense again, they let Zalgiris to score only 65 points in total. 2nd quarter was key to their win when Zalgiris scored just 5 points.
About the Real vs Efes game, it's always fascinating for me how basketball works sometimes. A team is up by 24 and controlling the game. Suddenly the momentum shifts and the other team makes a big comeback to cut it close or even take the lead, just to lose it again in the final minutes of the game. You see this so often, also in the NBA, and I wonder why. Is the team just exhausted after the big run or what might be the problem? Normally the team that lost the lead should be super nervous and the chasing team should be super motivated after completing such a big comeback. But more than often suddenly the game shifts again and it was basically all for nothing. So strange sometimes.
It's good question, such things happens quite often. I guess that being exhausted after making such big run might be one of main reasons. Then you start to make bad decisions in offense liketrying to rush too much when few points difference remains. And also it doesn't helps to keep big intensity in defense. And sometimes it's just small details... 
They could have won by a much bigger gap too if they didn't mess up in next quarter. 
I hope that you come to Turkey one day. Maybe we can watch a game together. 
At least have some meaning to your posts and not just to collect them, it's not that hard you know.
