How do you know that? Have you seen much of the league?I don't think that the Montenegro pro league is a higher level than the Big Ten. There are 3 NBA lottery picks playing in the Big Ten this year with another 2-3 first round draft picks. Sure, they are older, but the Montenegro league doesn't have athletes like Lendenborg and Morez Johnson.
Does the amount of athletes or lack make one a better league than the other? The SEC has better and more athletes than the Big Ten, but that doesn’t mean it was a better league and the Big Ten.
