actually i think the international diversity ratio in NBA is about 23%. i.e. 23% of the players playing in the NBA now are foreign born. http://www.theatlanticcities.com/arts-and-lifestyle/2013/10/remarkable-global-diversity-nba/7380/ La Liga's comparable statistic is about 41%. http://www.bbc.com/sport/0/football/24467371 The 2 statistics may not be completely comparable, but I just want to highlight that basketball is far more international than you may like to think.
