Serbia is a solid team with many experienced players and I think it is the time to win this tournament.
It's their best chance now because although the team USA is the favorites to win, I don't see them as a super team unlike the Roster they have in the past.
I like betting on the underdog but this dog has a chance of pulling out a win, and when it comes to experience, I agree with you that they have the edge as most of the players of the USA team are young players.
