I am getting it. Your team will have approximately 170 players. You'll see the drafted overall for all of them. You have 3 teams. That's 500+ players you can use to "get a better idea". That's seems like a big enough database to draw info from. And, yes, I know all of them won't be BL players. But you'll have the development pattern for the 2nd, 3rd, 4th and 5th year players. You have plenty to view, on your teams, to get what you want.
Why not?
Should I assume you're talking about players not drafted by you?
That's one of the drawbacks of 0 ADV. It's a lot more work, and not very precise, when trying to evaluate young players on other teams. My 53rd pick may be fantastic but the dumbass who picked 11th could have screwed it up. You can always go back and see how well he's drafted and make an educated guess from there but that doesn't mean he didn't F one up.
Now that I think about it, this is a good reason to NOT allow the viewing of drafted ratings. If you want to acquire players without a development pattern, pay for ADV.
