I haven't given up on Fab. It's stupid to do so. He was drafted as an extremely raw prospect. There are guys who aren't raw and are expected to transition into the NBA seamlessly, but still have a few underwhelming seasons before getting it. To give up on a raw prospect after one season spent in the D-League just doesn't make sense.
That being said, I haven't heard him make any significant strides in his development at all, and I certainly don't expect him to be a contributor for the C's this year. And despite our absolute lack of depth at the center position, I'm not even confident he'll even play for the C's this year.
