Since I don't fully understand what you're saying, I'll just tell you what I do. I rank everyone I think could have a BL career. Better players at the top(obviously). After the draft, I make a note of what pick those ranked players were when I drafted them. After a couple of seasons, I start removing the notes if it's apparent they won't be BL players. If they aren't BL players or won't be BL players, I don't care what their original ratings were.
