Idiocy exists in every field of play in the large spectrum we call life.
This list not only salutes the greatness of those overlooked, but the morons who overlooked them.
Perhaps I sound vulgur, but some of the greatest NFL athletes to ever play were passed up, by everyone, and signed off the board to come in as scrubs.
Personally, I would never want a top 10 pick in an NFL draft. You are more likely to get some pissant college kid thinking he's God and having his bigshot agent asking for record guaranteed money in longterm contracts, which roughly three to four years later turns out to be a move that gets you the idiot label, and rightfully so.
