According to IFBB Professional League & NPC rules :
American NPC Nationals's; each weightclass winner can be qualified to earn pro card .
###(even in bad condition,take a look at the pics of former NPC class winner in Iron man pro 2007)
But each Asian (European) weightclass winner can't be a pro !!
And American team in world championships 2006 ,70kg &75 kg 's placement are almost last !!
That would be due to the fact that the USA has the best competition in the world.
As for the American team placing last at the Universe, there's a good reason for that. The other countries sent their best guys; America did not.
The lightweights and middleweights, who turn pro at the nationals, go right to the IFBB. Most couldn't care less about winning the Universe (part of the reason, NPC has the Team Universe show).
When was the last time an Asian overall champion (let alone a mere lightweight/middleweight class winner) won an IFBB pro show?
