A new car loses value as soon as it leaves the car lot. I really don't understand why NFL teams value draft picks so much? It makes no sense to me. Groves for a fifth, Carriker for a late pick, Ginn for a fifth, Sheffler for a late pick, Boldin for a third? I bet as soon as any team picks a player in rounds 4 or 5 and then tried to trade him they wouldn't get anything for them. But for some reason prior to the draft the pick is like gold. I don't get it.
