The basketball tournaments of University Athletic Association of the Philippines (UAAP) Season 70 started on July 7, 2007, at the Araneta Coliseum with University of Santo Tomas (UST) Rector Very Rev. Fr. Ernesto Arceo, O.P. delivering the speech. Manuel V. Pangilinan of the Samahang Basketbol ng Pilipinas and United States ambassador to the Philippines Kristie Kenney were the guests. Former UST Growling Tigers basketball player Ed Cordero is the season's commissioner. The theme is "Winners All, Recreating the Value of Honesty through Sports" The Studio 23 coverage uses the theme "Madrama" (Tagalog for "full of drama"). Despite a 14–0 sweep by the University of the East (UE) Red Warriors in the elimination round, they were in turn swept by the De La Salle University-Manila Green Archers 2–0 in the finals after UE had a half-a-month's rest. De La Salle Santiago Zobel School (DLSZ) Junior Archers clinched their second championship by beating the Ateneo High School Blue Eaglets with their own 2–0 sweep. Ateneo took home the women's championship with their own version of a sweep against the University of the Philippines Lady Maroons.
