The second german league even today (back in the 90s it was even worse) in terms of quality is comparable to your local YMCA, Luka on the other hand won MVP of the Euro League, a league full of ex NBA players and proven european star players.

Just a quick example to show you how bad the German First League even today is, Malcolm Delaney was the league MVP in 2014, he played briefly for the Atlanta Hawks after winning his MVP and scored something like 6 PPG. Just keep in mind the best player in the second league is probably not as good as some of the worst players in the first league, and the best player in the first league is a guy who scores 6PPGon a tanking team. That's how bad the second german league is.
