Lithuania is set kinda low, I think that they could win a medal, unless they meet United States and Serbia in the 1/4. I think that they have some chances against Greece and Spain,they wouldn't be favorites though.
Well, we are never listed as favorites, but last time in World Cup we finished 4rth, back in 2010 3rd, what is not bad achievement. This year we played 2 friendly matches with Serbia and lost both times just in the last seconds. We have 2 NBA players Valanciunas and Sabonis, some solid Euroleague players. But one of the main problems that we don't have solid backup center. If JV and Sabonis will have fouls problem, we simply don't have replacement for them.
