1) Create a new Roster file. You can do this by saving your current rosters (even if they're the default ones). Be sure that this is something you're willing to overwrite!
2) Open your Dynasty File (My Docs>NBA Live 08>Saves>DYNASTY)
3) Select all the files and copy them.
4) Paste them into the roster file you created. Overwrite.
5) Load the rosters, and voila! You can now play with the other teams, do one-on-ones, do individual practice, etc.
Have fun!
