For Chiu and Kemark Carino types, the PBA is OK. They're well-suited for that game as a big, being asked just to defend the paint and rebound. As for Carino, just need to add strength without sacrificing mobility so as to be able to play 4, kind of like Almazan and Erram. Better nga if both went to Yeng.
But for Justine Baltazar, Kevin Quiambao, and Carl Tamayo types, that's where it gets murky, since guys that size with their mobility and skillset aren't that common in the Philippines. They need to be in a situation where they are still free to play as tweeners, not converted to traditional bigs. KBL's still a better option for them, with less world imports and all that.
