Del Rosario may be overaged like Gemao, Wagan, Pomelo Ball Esperanza, 6'4 Ples and 6'5 Lorenzo. If born 2006, they're all not qualified. A lot of (qualified) players of San Beda attended the tryouts like Ludovice, Balayan and Basty Castro (now all with UST) so I guess the information was properly given, it's their (or their coaches) fault if they didn't attend or were simply too old for this Gilas edition.
At the risk of sounding repetitive, "walang nang nag-attend ng Gilas tryout na malalaki". Pati nga ang very raw na 6'1 Olaes and very young (2009) 6'6 Prince Carino ng FEU nag pass ng first cuts but were eventually deemed not ready. For me, one of the (inexplicable) early cuts was 6'5 guard Escobido from UST as he seemed very similar to Edryn Morales.
FEU was well represented in the tryouts with 6'1 Olaes, 6'6 Carino, 6'4 Pasinos, 5'10 Godoy, 6'0 Raneses and 6'1 Brandon Yutuc (formerly of San Beda).
