NFL - yes. Almost all NFL players have attended a college, though not all graduate before they move up to the NFL. Association Football (soccer) - No. Very few professional soccer plays in Europe & South America have attended college. Most soccer players turn professional around the age of 18, so it's difficult to combine professional sports with a university education. Some do though (Steve Coppell is a famous example).
