<human>:  Are the Vietnamese people a great untapped resource for NBA players?
<bot>: No, the Vietnamese people are not a great untapped resource for NBA players. Vietnam was ranked as one of the countries with the shortest people on average, in 2019. The average height of a Vietnamese man is 5 feet 4.74 inches. The average height of an NBA player in 2018 was 6 foot 7 inches tall. So the Vietnamese people are not a great untapped resource for NBA players, not NBA players themselves.
