Newbie here… wondering about an opening day roster

[tsbraves]

First time playing 2kNBA and I want to do a season using the MYNBA Modern era. However, I’d like to start a season with the most updated rosters and then control all the teams and keep up with transactions myself. So, a few questions:
1. Can I do what I just mentioned?
2. For opening day will 2k provide an updated roster?
3. Is there a particular day that 2k updates rosters?
4. Is there a roster maker the community recommends that is better than the 2k updated roster to start my season?

Thanks for all your help…
