Before (end of 00-01 season, via archive):

After (current index):

Just doing a quick scroll through, I noticed Ruben Patterson also had the same thing happen (g/g to y/g without change to any current ratings).
This is completely new to me and everyone else (Wig included) who have been around running the game. I'm going to reach out to the developers about this as well with screenshots (of which I will take shortly). Again, their current and potential # rankings did NOT change, but the colors did. After looking into it, we have a theory that maybe the large influx of talent from this draft may have had some impact on how the ratings are color categorized... I.E. we had 12 new blue potential players and another 10 green potential guys coming in, with very little retiring. This would lead us to believe that the thresholds for the color ratings are FLUID in that it depends on how much talent currently exists in the league.
Again, please do not lose your cool or flip out, because I'm at a loss just like the rest of you may be. So hopefully we get some positive information from the developers regarding this issue and can at least get some clarification.
Sorry for the inconvenience and confusion, guys.
