Real, Barcelona and Olympiacos games were all very good. Papaloukas was phenomenal (Fener never understood how to stop him and at some point they just quit); Vesely, Mirotic and Tomic showed they can perfectly have a NBA future; Maccabi and Barcelona showed they are the 2nd best and best team in Europe - Barcelona's ability to resist to Maccabi's full-court pressure makes them clear favourites in a final between these two teams though.
Olympiacos vs. Montepaschi - Will McCalleb play? If so, Siena in 4 games. If not, Oly in 5.
Pana/CajaLa/Rytas vs. Maccabi Electra - Maccabi will beat any of these teams. Caja Laboral would be their toughest opponent. Maccabi in 4 or 5.
Real Madrid vs. Fener or Valencia - Valencia needs to beat Fener by at least 3 points. I think Fener lacks mental toughness and chemistry, but Claver's missing is a bigger deal for Valencia. Anyway, with HCA Real Madrid should beat any of these teams. Real in 5 vs. Fener, 4 vs. Valencia.
Barcelona vs. Pana/CajaLa/Rytas - Barcelona in 3 or 4.
