Below is a link to a fascinating study done in 2007 for those of you with a 1/2 day to waste regarding what a couple of guys did researching the who draft trade value chart often referenced in the NFL draft circles. What this study shows is how teams over value high picks versus lower round picks. And that the trade value board established by the Cowboys in the 90's is way too skewed towards higher round selections for value. Thaler and Massey Study It is a very good read (52 pages). And though I don't want the Broncos to trade out of the 12th pick if Maualuga is on the board, it does give some good justification for trading down with teams that over-value a top 15 pick.
