"if a zero adv scout team receives an offer for a 1st or 2nd year player.. or from a team that has poor training and/or poor coaching at the low levels... the zero adv scouter is handicapped big time."
It's more true that a new owner who receives an offer for any player from a veteran player is handicapped big time. Unless the veteran is making an offer that clearly deals away from a deep position to fill a hole and the offer does the same for the recipient, chances are the veteran owner is going to come out ahead. A new owner shouldn't go to 0 ADV until he understands the ratings, and should be cautious about trades until the same time.
A veteran of 0 ADV who spends some time researching is not handicapped when making a trade for a 1st or 2nd year player. You can tell a lot from IFA bonus, draft position (also taking into account the owner's draft tendencies and skill), makeup, a few in-season development cycles, and other factors.
