I personally went to the roster editor, downloaded his roster and mass edited all of the FAs to be 59 years old and 40 OVR so they all retired at the end of season 1. I didn't want to mess with a mix of a 99 rated LeBron playing with the 90-91 season and so on.
That said I LOVE this roster, paired with all of the historic draft classes. I current have a Celtics team featuring Reggie Lewis, a rookie Shaquille O'Neal I drafted, and Karl Malone whom I signed as a FA. All of the players I grew up with.
