When the Realtors took the first overall draft right in 2006, they did not hesitate to pick Kelly Williams over two-time UAAP MVP Arwind Santos, who was later picked second overall by the Air21 Express.
After the 2008–09 Philippine Cup, Guiao resigned and the team was renamed as the Barako Bull Energy Boosters.
