I know that's a popular viewpoint here - KTD says the same about Sammy - but I disagree with it as a team-building approach. Yes, you need to collect star players. But no, you can't do so without considering the limited draft and cap resources you have, and the overall context of your roster. You also have to consider the value of the player in the context of the talent pool available at the time; BB wrongly believed there were other comparable options at WR in that draft (he was wrong); some of us rightly believed that the talent that Sammy possessed wasn't sufficiently unique considering the depth of receiver talent in that draft (OBJ, Evans, etc.) - we may have been right.
Scouting is about acquiring talent.
Team-building is about collecting the right talent at the right time, using the right amount of resources.
Doug Whaley is a good scout. He is a horrible team-builder.
If the Falcons made that trade without already having Matt Ryan on their roster, it would've gone from incredibly expensive to downright idiotic. See: Sammy Watkins.
