use him with updated rosters?
Situation: Just finished my first season in My Career using the last NBA 2k13 official roster update. I now want to update the rosters (using the latest UBR) and keep the progress (i.e., attributes/skills, upgrades) of My Player. I don't care if I have to start over My Career -- I really just want to preserve the improvements I've made to My Player and either continue My Career or start a new My Career using updated rosters.
Is that possible?
