I don't think that's an actual brother. PJ is a Jr. I don't think he has an older brother. And his dad is like 53 yrs old. His sister's instagram never mentions an older brother. I think it's Sal Frazier https://www.instagram.com/salfrazier/
I pray for PJ and his family. Go miss as many games as you need, family is more important than basketball. The rockets will hold it down for you!
