In my opinion, Haplogroup I2a1 is most likely to be the "original" Y-Haplogroup associated with the Basques. I think so for several reasons: first off, we know that I2a1 was present in western Europe in the Neolithic (in Treilles), alongside G2a. In my opinion, the fact that Treilles was mixed G2a and I2a1 does by no means contradict the fact that modern-day Basques have virtually no G2a.
The other issue is that apart from Sardinia, the Basque country (and moreso, Aragon) has one of the highest concentrations of I2a1.
