The FIBA websites are currently inoperable, but I thought Oggi was shown getting major minutes for Serbia's either U-20 team or earlier at U-17 in international comp. Besides the team in Bosnia he played for last season, he earlier was part of Partizan Belgrade, a major well known Euro sporting club, probably on their youth team. I also found a SI story pointing to the interest Kansas coach Bill Self (among many ranked programs) had in the Yugo. His height is listed as either 6-5 or 6-6 in all the sites I saw, but that could have been 17/18 y.o.
