Manotoc is the son of Ricardo Manotoc[5] and the former Nena Arguelles La'O.[6] His father was a realtor,[5] while his mother belonged to the prominent La'O family.[6] Two of his uncles - Raúl Manglapus (who had married Pacita La'O, a sister of Manotoc's mother) and Eugenio López, Jr. (who had married Conchita La'O, another sister of Manotoc's mother) were prominent critics of Ferdinand Marcos.[7]
PBA career
As head coach
Manotoc began his coaching career in 1977 with the U/Tex Wranglers in the Philippine Basketball Association (PBA). He was the Wranglers' team manager at the time when head coach Narciso Bernardo suddenly resigned after the 1977 All-Filipino Conference. Manotoc made his coaching debut during the 1977 Open Conference and immediately brought the Wranglers to a runner-up finish against Crispa, in the franchise's first finals appearance. Manotoc gave the Wranglers two PBA Open Conference championships, in 1978 and in 1980. He admitted that besting Toyota in 1980, felt like an achievement since they were down by four points with 16 seconds remaining in the fourth, but ultimately forced overtime and won.[8]
A few decades later in June 2020, he revealed that during his championship stints as head coach of both U-Tex and Crispa, he did not charge the team, in terms of salary, and his bonuses that he had earned, were instead given to his father.[9]
As PBA Deputy Commissioner
Manotoc briefly served as deputy commissioner of the PBA in 1985 under commissioner Mariano Yenko.
PBA Hall of Fame
Manotoc was inducted into the PBA Hall of Fame on October 2, 2011.
