Oh he wouldn't have been the centrepiece. I think a guy like Hunter Harvey (offered) or Raimel Tapia (sort of offered) would be more valuable than Niese. Add in the first rounder and Niese might have been the third or fourth best asset.
.... If you're pessimistic about Niese. He has some unattractive aspects for sure, but he remains extremely fantasy relevant and somehow he's staying on the field, still young, never really did throw hard.
