The problem with DAdmiral/analyzed is that he doesn't value blood ties or descent (Or whatever we should call it. Damn, I'm not particular about semantics). He thinks that the case of Tyler Harris, who has no blood ties with Qatar (basta naglaro lang sa Qatar local pro league ng ilang taon), is just the same as the case of say a Chris Newsome (whose father is an American & his mother being a natural born Filipino therefore Chris Newsome has blood ties with Philippines). For as long as FIBA declares one player as eligible as a local player of a particular country, that's OK with DAdmiral.
The thing about DAdmiral is that he has a very liberated mindset that things like blood ties, race, athnicity, descent, ancestry hardly matters for him.
Perhaps he won't even mind that one day Qatar would be parading a team composed of Martians for as long as they obtained Qatari passports prior to their 16th birthday.
How to we define "blood ties"? DNA/Genes
If that is the case, then we might as well consider Taiwanese Aboriginals, Chamorros, Malagasy people because they
share the same ancestral DNA as us. When they take 23andMe, they will come out as predominantly "Filipino and Austronesian" even if that connection was 4,000 years ago.
One has to remember that even by our constitution, being Filipino is not about "blood ties". It is really about the paper trail and if you have valid claims to PH citizenship if you can prove that at least one of your parent was a Filipino citizen upon your birth.
If for example one was already past the age of 18 when the dual nationality act was passed, and their parent lost their Philippine citizenship before they were born, the government will not recognize them as PH citizens. If the PH government does not recognize them as PH citizens due to not meeting the requirements to claim PH citizenship, "ancestral ties" is useless.
The PH nationality laws is NOT like that of Israel or Ireland where if you can prove you have "Irish DNA" or "Jewish DNA" , you can claim citizenship in those countries even if you are 20 generations removed from those places. The Philippines defines Filipino not as ancestry or ethnicity or bloodline but solely on legal grounds.
If we are going to overemphasize "ancestry", "blood ties", "descent" we might as well tell people like Geo Chiu or Isaac Go to represent the PRC because that is the country they have "blood ties" to. After all their grandparents/parents are migrants from China not more than 100 years ago.
If Gabe Norwood's mother (who is "half" Filipino. Norwood is "one fourth") did not give birth to him when she was a minor, Gabe will not be able to claim PH citizenship unless he gets a sponsor that will bribe someone in the PSA or DFA. Small legal technicalities matter a lot.
Justin Brownlee can pretty much get his children to be part of a future Gilas team (granting that he processes their derivative PH citizenship while they are minors) and be considered a local despite the lack of "blood ties". His children's ties to the Philippines is not from "blood" or "ancestry" but from the fact that Brownlee is legally (aka paperwork) a Filipino. JBLs grandchildren can pretty be much as natural-born Filipinos as Oftana or Carl Tamayo despite the lack of what people refer to as "Filipino" blood which is just Austronesian ancestry (which is shared in large part of the Pacific World).
The problem with Qatar is not the lack of "blood ties" but lack of any kind of non-transactional relations between their players and the country they are representing. Harris neither has a parent who lived in Qatar nor did he prior to becoming a mercenary for them. If Qatar fielded someone whose both parents hailed from the Philippines but grew up in Qatar, that is a significant non-blood ties to Qatar.
It is important to note the origin and history of the term Filipino. The birth of the national consciousness of being a Filipino did not originate from the people we think as having "Filipino ancestry" (Austronesian peoples) but from the local-born Europeans. The first known person to refer to himself as a Filipino in a nationalistic way was not an "indio" but someone of European descent - Luis Rodriquez Varela. He was even known as
El Conde Filipino.
The movie Gomburza shows the concept of Filipinoness very well - particularly during the conversation of Pedro Pelaez and Jose Burgos - and both of them are of European descent.
