work is work, 3x3 is not a bad option especially for those who have borderline skills and limited real world skills (not to mention didnt take college seriously).
not everyone is cut to play in the highest level of pro play in the country, similar to the nba, hundreds of d1 ncaa schools plus numerous international prospects yet only 30 teams, the cream rises to the top and only the fit should belong to the PBA, thus it should not add teams for the mere sake of accommodating all the displaced and the aspiring athletes, i would rather have the league address parity first before adding teams. i think the days of midget ball would end if talent in the league is distributed evenly among teams.
its similar to any other career actually, only the select few, the best of the best, gets the highest posts. Corporate or academe, public or private sector, only few slots are available and only the best (in theory) should hold the post.
i think adding a team or two would be enough (indy team ah not farm team) but more than that would saturate the talent pool, just like how the mpbl expanded too soon which led to an awful product.
personally though i don't pity that much those who did not make the league, they had their scholarships in college, they should be equipped with the employable skills outside basketball, like the rest of us. Plus, its a competitive environment, its high level pro play not a charity of affirmative action program for the aspiring pros
