Whatever you see - before - the draft is based on your HS or Coll scouting. If you have say $20 in HS and $10 in College, if the player is HS, his projections should be fairly, but not absolutely perfectly accurate - assuming you get the player plenty of playing time, give him regular promotions to the proper level, he has good coaching, and stays healthy. If the player is College, $10 million isn't going to give you consistently accurate ratings.
After the draft you will see this -
Current ratings are totally accurate. Past ratings are totally accurate. Projected ratings are based on Advanced scouting.
Bottom line is this - beef up your draft scouting for either HS or College (or both) to at least $16 or more. Do your pre-draft HW to find players that will be productive. Then start them off at an appropriate level, and get them playing time. Don't worry about Advanced Scouting. They won't be BLers for at least a few seasons and a lot can happen before then.
