Yes, a healthy Giannis can make a difference,without him it will be very difficult for them to achieve anything. France can do it the players you mentioned will be badly missed, but they still have that quality. To be honest, i haven’t been following Spain. In my opinion, Serbia and Germany have the most well prepared teams.
That's true, and that's why they have the better odds for winning the tournament. Even if I didn't see any exhibition game, Serbia and Germany are among the 2 teams that it will be a surprise not to get any medal. Which one will get the gold is a different and early story to discuss. For me, the "riddle" is which teams will follow them. France and Spain will face difficulties with such absences, that's for sure.
For me In my opinion, the main favorite is Serbia also, and Germany is the second best. Another medal contenders are France, Spain, Lithuania and Greece. Latvia as
host nation will try its best surely
-, and maybe can become the revelation of the tournament. Other participants are pretty mediocre. Cyprus - as an "isolated island" here -
will try not to lose by more then 20 points in every game
-, but local supporters will have an unique occasion to follow quality basketball in any case.
