If this analysis must be as short as possible - UNICS is better team. Simple as that. But i will explain my opinion with more details.
At the begining, they showed in last game between this two teams difference in quality with easy 20 points win. Many expect today they will enter match relaxed as they have some huge advantage from first match, but i am afraid its not going to happen. UNICS will play this match with full potential as they are serious team, and not going to gamble with hardly earned advantage from first match.
They have better players on almost all position, and the most important advantage is coach. With all reaspects, sir Vlada Jovanovic is not coach for this rang of competition. He is good for young selections, for some east european leagues, but not for serious competition with serios teams as EuroCup is.
Lokomotiv Kuban - UNICS, away team to win. Good luck!
