The best Gilas prospects in the PBA are mostly in the 29-year old & above age category while those Gilas prospects in the B-league & KBL are in the early to mid-20's age category.
I say the PBA guys represent the present of Philippine basketball while those in Japan, Korea & the current college players represent both the present & future.
Here's the best guys from the PBA: Castro (1986), Abueva (1988), Brownlee (1988; NP), June Mar (1989), Newsome (1990), M. Ahanmisi (1991), Alas (1991), Terrence (1992), Scottie (1993), Perez (1993), Bolick (1995), Arvin (1995), Oftana (1996), Malonzo (1996), Navarro (1997), Arana (1999)
In the B.League: Wright (1991), Parks (1993), Kiefer (1993), Thirdy (1996), Dwight (1998), RJ (1999), AJ (2000), Kai (2002)
In the KBL: Gutang (1997), Abando (1998), SJ (1999), Juan GDL (1999), Oczon (2000)
In college: Quiambao (2001), Briones (2002), Policarpio (2002), J. Cortez (2002), Lopez (2003), Mason (2004)
Carl (2001) and Heading (1996) are free agents. So are Cansino (1999), Nelle (1998), and Jerom Lastimosa (1998).
I put in the birth years instead of present age so that we can better project by 2028. And, over half the PBA guys are currently 30 and above.
