Information asymmetry is a term used in contract theory and economics to describe situations where one party has more or better information than the other.
Two parties sharing such an information asymmetry are NFL teams on one hand and fans and draft media on the other hand.
Over the years, fans and draft pundits have created ever more complex schemes, strategies and outright fantasies about what they think NFL teams should do. Draft preparation is no longer about trying to predict what teams will do, today it is much more about telling teams what they should to do - and then criticizing them for failing to follow whatever mock draft or big board somebody concocted.
