Quite an upset night in the Euroleague huh, who would have thought. 4 home teams, 4 home wins, 3 of them by underdogs. Obviously the HUGE upset by Virtus against Olympiakos stands out, didn't see that happen! First Olympiakos takes the lead with 6 seconds to go and then Marcus Carr with the buzzer 3 to win the game, that's crazy!
Paris also surprised me, I imagined Zalgiris would win this one easy since Paris still hasn't found it's rhythm yet, but in the end they got their first win of the season while Zalgiris, despite a strong roster, only stands at 1:2 now after 3 games.
Despite being a small underdog I thought Efes would have a solid chance at Red star, but in the end they have been the only dog that didn't win.

It looks like Anadolu Efes will struggle on the road this season. Both teams shot very poorly from three-point range yesterday; Anadolu Efes attempted 26 three-pointers but made only six.
While Crvena Zvezda secured their first win, Anadolu Efes suffered their second defeat.
For me, the result of the Virtus vs. Olympiacos game was a bigger surprise. I didn't watch the match, but as you mentioned, Virtus won thanks to a last-second three-pointer. Things like that happen in basketball.
It is also interesting that Real Madrid has yet to record a win, though all three of their losses came in away games. This suggests that Real Madrid, much like Anadolu Efes, will face difficulties playing on the road.
