Zydrunas Ilgauskas is the second tallest right now and Yao Ming is the second tallest NBA player ever.
The tallest player i think is Yao Ming
The NBA player who paid for 80 cows for his wife and is the tallest ever in the NBA is Manute Bol. Bol is a native of Sudan.
Previous tallest african-american basketball player in the nba was Ralph Sampson who was 7'4
manute bol is the tallest one ever, but currently the tallest nba player is regan crocker at 9'9!! Actually it was Gheorghe Muresan who was the tallest player ever, at 7'7", and regan crocker isn't an NBA player, and the tallest man ever was 8'11", so he can't be 9'9". Unfortunately, Manute Bol died at 7'6".
i think it is manute bol
