Eagles under the leadership of Frankie Rabat captured the 1953 and 1954 NCAA titles. 1955 was the year when the Crispulo Zamora trophy was awarded to San Beda when they defeated Ateneo for the coveted crown. The Blue Eagles again prevailed with 1957 and 1958 back-to-back crown only to be defeated by San Beda in 1959. The rivalry continued in the 1970s, when their sons, Chito Loyzaga and Louie Rabat met in the NCAA. The rivalry came to an end in the 1977 Finals series. In Game One, a brawl ensued among fans of the competing teams, which led to the third game being played behind closed doors, with San Beda winning the basketball championship, after Ateneo's last second shot was ruled invalid. The violence surrounding this championship series, coupled with the violence that was plaguing the league, led to the withdrawal from the NCAA of both Ateneo and San Beda. The Blue Eagles left with 14 seniors titles, a record for the most number of seniors titles that would only be tied and surpassed decades later. San Beda later won its 14th title in 2008. The Ateneo de Manila joined the UAAP, while San Beda College eventually came back to the NCAA. La Salle–Letran In the 1970s, La Salle started its own rivalry against Letran. Letran then had 6 championships while La Salle got its fifth championship at the expense of Letran in the diamond (75th year) championship series. De La Salle College then was managed by Ambassador Eduardo Cojuangco, a known crony of then President Ferdinand Marcos. Coincidentally, Cojuangco controlled the FIBA-recognized Basketball Association of the Philippines (BAP) and was appointed by Marcos as project-director for basketball. The rivalry came into a climax on an August 16, 1980, La Salle–Letran game. The Letran bleachers were totally unoccupied minutes before the game began; Letran school authorities would not let their students get inside unless De La Salle's team manager's "guests" leave the south end bleachers that are part of the Letran stands. The group moved over to the north end (La Salle side) after talks between Ambassador Cojuangco and Letran Rector Fr. Regino Cortes. Only then did the Letran bleachers fill up. With the game on the way, Letran was toting a 22–18 lead when they called a time-out halfway through the first half; then, the south end reserve section (Letran side) erupted with at least five burly men
