Do you have tapes/highlights of yourself?
Like what they said, get an agent who's well-connected to PBA teams here. If you're lucky, they may offer you a tryout. If they like you, they willprobably hide you from all the other teams so they can officially sign you via the draft.
Mark Caguioa and Jared Dillinger worked out directly for Ginebra and TNT respectively without passing through the pre-draft camps or the PBL. They werebasically guaranteed to be picked by both teams that's why they did not bother going through other workouts. Both teams shielded them from the public aswell.
If you're not good enough for the PBA yet, there's always the smaller leagues like PBL and Liga Pilipinas. TNT has its unproven Fil-Ams playing fortheir Liga Pilipinas affiliate, Pampanga Buddies.
I'm not doubting you bro, but if you're any good, I'm pretty sure the scouts would have heard of you already.
Anyway, send me a tape or get in touch with me via PM. I can forward your vid to the folks at TNT.
