Well Bartol to speak about Dominican Republic form in prisme of Norceca is without sense because only USA has non-Norceca level so You may beat Cuba- as in qualification to OG or Puerto Rico- as in 2009 Norceca Champs also in bad form.
If We speak about Olympic Games- when did You see good form? During matches vs Algeria or Great Britain?
No, form doesn't mean results. Form means level of the game. In Olympic Games Dominican Republic was on good form, but they weren't enough good to beat Italy or Russia (they played good matches against them) or USA.
It doesn't matter... they won NORCECA title 2009 with good form and silver medal in 2011 in good form too, so sorry. Don't forget that this is still young team. The best performance will be in Rio or even in 2020. Young players are so talented, so just wait for get experience and will be ideal.
