i have no idea who he is, but here's some info from Project Spurs:
The 25-year old Aguilar is a former Philippine Basketball Association No. 1 draft pick and has been working out for some D-League teams this summer but his goal is to make it into the NBA.
He is 6-9, 225 lbs., and played at Western Kentucky University for two seasons before leaving in 2009. Since then, he has been playing in the Philippine Basketball Association.
