Look I am not sure who was a better shooter but there is a clear difference in approach in European basketball and the NBA. People think that the teams are more oriented to stars like they are in the NBA. This is quite often not true. Teams in Europe are built to play team game and in a lot of ways be an equal opportunity offense. Of course there are exceptions as there will be more plays called for more established stars.
Young players, unless they are playing on a team known for developing young players and giving them big responsibilities (e.g. Mega) they are played as role players, no matter how talented they are. Frank is 18/19 years old. For a team not known for their player development, he is not going to get many shots. Bogdanovic was the most talented youngster at Partizan when he was 18 but he was riding the pine more often than not and did not get many opportunities to shoot and this is for a club that is well known for player development throughout Europe.
