Picture this...
You have 3 scouts- 1 college guy, 1 HS guy and another pro guy.
The 2 amateur guys are full time, work year round and do a good job (20 mil budget)
The pro guy is part time and doubles as a McD's line cook (0 budget)
During the draft, you see the ratings that your amateur guys have come up with and post draft, they're automatically transferred into your 'pro' database that your pro guy has compiled, and he's an idiot.
So basically, everyone is right, copy and paste your draft ratings into the player notes right after the draft and use them as a reference.
