According to hoopshype.com Pendergraph is under contract for $854,389. I think I read somewhere that it isn't guaranteed, but I could be wrong on that.
The brother combo that people are not mentioning is the Wilkins brothers. Dominique and Gerald. The Hansbrough's would be the 4th brother como to play on the same team.
I think the Pacers will only carry 14 players. Most likely they will cut either OJ or Ben, but it wouldn't upset me if they released Pendergraph.
