Danny,
I've had a couple of figs do that (here in NJ) over the last couple of weeks. The outcome was varied. At least one tasted perfectly fine. Some tasted a bit fermented -- not really sour, but just not quite right. I was traveling and let some sit on the trees a few days longer than I would have, so I think that contributed to it. They were getting overripe...which I think would have been OK if they weren't split; but since they were split they were starting to go bad. One was sour enough that I spit it out and didn't finish it. Many of them only tasted "off" near the exposed split -- the farther you got from the split, the better they tasted.
It is a gamble. If you pick it and eat it underripe, you know you won't be happy. If you let it ripen, there's a chance it will be great and a chance it will be a little "off", and a chance it will be downright sour.
