Valerie Adams half-brother - Steven Adams (Pittsburgh) declares for NBA draft. Doesn't seem like they are close as according to Pitt, he is "one of 18 siblings, six of whom played basketball for New Zealand...All of his brothers stand around 6-10 or 6-11 in height and his sisters are 6-5 or 6-6 tall.."
When his dad died, he was living on the street and all.
That being said, it's kind of sad that some guy who only averaged 7.2 ppg will likely be a 1st round draft pick and make more money than his sis who is a double Olympic champ.
