For future reference, there wasn't really a need to create another topic when you've already brought up the issue
here.
In short, NBA Today occasionally misses updates, at least on the PC version. In my experience it's updated more often than not, but occasionally it's outdated. As I said in the previous thread, 2K doesn't have the best track record in that area. Whenever they're having server issues or otherwise not sending through the updates, there's nothing we can do except twiddle our thumbs and wait.
