Accomplishments: Paul: Two-time NBA champion; Marc: Olympic silver medal
The Gasols have come over from Spain and made quite a name for themselves in American basketball. Pau had already established himself in Spain before he came over to the US in 2001, winning Rookie of the Year for the Grizzlies and later taking home back-to-back titles with the Lakers in 2009 and 2010. Marc actually played his high school ball in Tennessee after the entire family moved to Memphis when Pau was drafted. He played for two years in Spain before returning to the US, where he has evolved into a solid center for the Grizzlies.
While neither brother is known for his toughness, they both have signed contracts worth upwards of $60 million, so it's kind of hard to argue with their methods.
