The current NBA 2K14 roster available on all platforms appears to be four to five days outdated. Recent signings of Jorge Gutierrez, Reggie Williams, Royce White, Justin Hamilton, and Tony Mitchell have still not been completed.
Nothing much has changed since the last update. I just thought I'd put this up for those who want the latest offline update package for the PC version. You can install the roster and online data files manually by downloading the patch below.
